A 32gsm flat-bottom, 1-4 cup paper filter shaped for the DragonFly Tri-Spin FS Flat Dripper (390ml), for greater consistency with a deeper brew bed

The DragonFly 220 Flat-Bottom Paper Filter from DragonFly Design Center is a 32gsm virgin wood pulp filter made specifically for the DragonFly Tri-Spin FS Flat Dripper (390ml). Its pleated, cake-style form opens into a broad flat base matched to the dripper’s geometry, so the coffee bed builds deeper and more uniformly for consistent percolation. Each pack holds 50 filters.

How the 220 Filter Fits the Tri-Spin FS

The filter is designed to the specifications of 390ml Tri-Spin FS. The dripper’s 20 raised ribs hold the pleated walls in shape so the paper does not collapse against the brewer wall, while the flat base sits over the Tri-Spin hollowed base, which distributes outflow across several exit points instead of one central orifice.

With the paper seated evenly, the bed settles at a consistent depth and the water meets the same resistance on each brew. Flow rate and contact time stay repeatable, so when total brew time or extraction shifts, you can trace it to grind size, dose, or pour structure rather than the filter.

A deeper bed also lengthens the path water takes through the coffee, which extends contact time during percolation and supports a fuller extraction at a given grind setting.

Product Details

Brewing with the 220 Filter

Pre-wet the paper with hot water to seat it against the ribs and preheat the brewer, then discard the rinse water before dosing. You can do so by first adding a small amount directly to the center of the filter to set the base even. As the water moves up towards to folds, add more water in spiral motion to thoroughly rinse the paper.

Level the bed before the bloom for an even drawdown. Switch open for percolation, or switch closed for a full immersion steep before drawdown.

Specifications

The TIMEMORE × Millab M01 is designed for clarity - from the external dial, to the step-adjustments, to grind uniformity, the Millab M01 maintains clear operation - allowing your coffee to speak through with ease.

Five Stages, One Grinding Path

Unlike a traditional conical burr, the Pineapple Burr uses a tapered profile that spreads grinding work across multiple cutting zones. Coffee is reduced more gradually, helping minimize abrupt fractures and unnecessary fines. Developed through TIMEMORE's specialty grinder lab, the M01 introduces a new 44mm Pineapple Burr designed around a longer grinding path. Instead of reducing coffee in a single cutting stage like a conventional conical burr, the Pineapple Burr progressively breaks beans down over five stages before they exit the burr set. This creates an effective cutting path measuring approximately 60mm: around 50% longer than a conventional 44mm conical burr and improves particle consistency by approximately 10% when compared with the company's S2C-042-III burr.

While remaining a compact 44mm conical design, this allows it to approach the effective cutting distance found in many 64mm flat burr grinders. The result is a more controlled particle distribution while maintaining the compact form factor of a hand grinder.

On complete turn of the dial covers grind sizes from espresso o French Press.

Built Around Tight Tolerances

Consistency begins with alignment.

TIMEMORE specifies a burr gap tolerance of 0.0725mm, paired with custom P7 bearings developed specifically for the M01 platform. Together, these components are intended to minimize burr movement and maintain alignment throughout the grinding process.

Precision Adjustment

The M01 features an externally mounted adjustment dial built from five machined metal components.

Each click locks positively into place, allowing grind settings to remain consistent between brewing sessions. The stepped adjustment is designed to provide precise control across espresso through coarse brewing methods without accidental movement during use.

TIMEMORE states the grinder offers up to 100 micro-adjustments across a single rotation of the adjustment dial.

Thoughtful Details

Beyond the burr geometry, the M01 incorporates several practical design features that improve day-to-day use.

• External all-metal grind adjustment dial
• Click-lock adjustment designed to resist unintended movement
• Threadless swivel-lock catch cup
• Silicone base for improved stability while grinding
• 51-component all-metal construction

A 255ml bone china flat-bottom dripper for 1 to 2 servings, made to sit on a transit base for switch-controlled brewing or a bamboo holder for a standard pour over

The Tri-Spin CT Flat Dripper from DragonFly Design Center is a new bone china flat-bottom pour over dripper built to close that gap. It starts from the CT62 conical dripper and rebuilds it around a flat bottom, with a grooved inner wall and DragonFly's Tri-Spin base.

How the Tri-Spin CT Manages Flow

The inner wall is a flat surface cut with 12 long grooves and 12 short grooves. The filter paper adheres to a larger area of the wall, so there is less room for water to bypass the bed and more of each pour passes through the grounds.

The grooves act as flow guides and pressure relief channels, which keeps the drawdown smooth and the extraction even across the bed. The result is a even extracted cup with clear layers of sensory expression.

At the base, the Tri-Spin hollowed design with multiple grooves spreads the water's exit points to avoid concentration in the center. This reduces the risk of the clogging and helps water move through the whole bed. This matters even more with larger doses, where localized over-extraction is more likely.

DragonFly developed the CT Flat with competition brewing in mind, where a stable, repeatable extraction counts for more than speed.

The Shanwen Jia Exterior

The outer wall carries the Shanwen Jia (山文甲) pattern first used on the CT62. Shanwen Jia, also known as Shanwen Armor, is a Tang Dynasty armor recognized by its repeating mountain pattern. On the dripper, that pattern wraps the outer wall as a continuous geometric repeat.

The exterior is the link between the two brewers. The CT62 pairs it with a conical interior, and the Tri-Spin CT pairs it with a flat bed and a grooved wall.

Product Details

Brewing with the Transit Base or Bamboo Flat Dripper Holder (Purchase separately)

Paired with the DragonFly Flat-Bottom Transit Base, the dripper brews two ways. With the transit knob open, it runs as a flat-bottom pour over and gives a clean, filter-style cup. With the switch closed gives a fuller, immersion-style cup.

You can also choose to brew with a Bamboo Flat Dripper Holder – using it as a traditional pourover dripper.

It holds 255ml, brews 1 to 2 servings, and takes foldable flat-bottom filter paper or 185 flat-bottom paper filters.

The Groove Structure and Tri-Spin Base

•       Groove structure: Twelve long and twelve short grooves on a flat inner wall let the filter sit closer to the wall while still guiding flow and relieving pressure.

•       Tri-Spin hollowed base: Disperses the outflow instead of concentrating it in the center, which reduces clogging at larger doses.

•       New bone china body: Heat resistant to 120°C (248°F). Safe for dishwashers, microwave ovens, and dish dryers.

A 280ml bone china flat-bottom dripper for 1 to 4 servings, made to sit on a transit base for switch-controlled brewing or a bamboo holder for a standard pour over

A flat-bottom pour over drains evenly when the coffee bed stays level and water can exit across the whole base. Uneven flow usually starts where the filter meets the brewer: the paper folds against the wall, fines collect in the center, and the middle of the bed slows while the edges drain through.

The Tri-Spin FS Flat Dripper from DragonFly Design Center, also known by its Chinese name 三旋空玄武 (Xuanwu), is a new bone china flat-bottom brewer designed to keep that flow even. Its transit base lets you brew as a standard pour over, or close the knob and steep as an immersion.

How the Tri-Spin FS Manages Flow

Inside the dripper, 20 raised ribs hold the filter paper off the wall so it keeps its shape through the brew. With the paper supported, water moves through the bed at a more consistent rate, and results vary less from one brew to the next.

The wall angle is set to keep the flow rate quick while still allowing a finer grind. A finer grind raises extraction yield, so a faster drawdown can still reach a full extraction and keep a clear, layered flavor.

At the base, DragonFly's Tri-Spin hollowed design spreads the water's exit points across the base rather than concentrating them in the center. This reduces clogging and keeps water moving through the whole bed instead of stalling in the middle, which matters most at larger doses where localized over-extraction is more likely.

The dripper received a German Design Award in 2026.

The Shanwen Jia Exterior

The outer wall carries the Shanwen Jia (山文甲) pattern first used on the CT62. Shanwen Jia, also known as Shanwen Armor, is a Tang Dynasty armor recognized by its repeating mountain pattern. On the dripper, that pattern wraps the outer wall as a continuous geometric repeat.

The exterior is the link between the two brewers. The CT62 pairs it with a conical interior, and the Tri-Spin CT pairs it with a flat bed and a grooved wall.

Brewing with the Transit Base

With the Transit Base open, it brews as a fast-flowing flat-bottom pour over and gives a clean, filter-style cup. With the switch closed, water stays in contact with the grounds until you open it, which gives a fuller, immersion-style cup.

Immersion is a forgiving starting point while your pour technique is still developing. The open setting gives experienced brewers direct control over pour rhythm and timing.

You can also choose to brew with a Bamboo Dripper Holder – using it as a traditional pourover dripper.

DragonFly Tri-Spin FS Flat Bottom Dripper - 280ml brews 1 to 2 servings, and takes 185 flat-bottom paper filters. It is available in Shell Pink, Black, and White.

The Tri-Spin Base and Rib Structure

•       Rib structure: Twenty raised internal ribs support the filter paper and hold its shape through the brew.

•       Tri-Spin hollowed base: Spreads the outflow across the base instead of concentrating it in the center, which reduces clogging at larger doses.

•       New bone china body: Heat resistant to 120°C (248°F). Safe for dishwashers, microwave ovens, and dish dryers.
