Modular Drawer System

Modular drawer units as big as you need. From a single drawer to a whole wall, customize them exactly to your needs.

Make one compact home for loose hardware, supplies, tools, knick-knacks and more. The frames clip together and stack neatly together to make a cohesive and aligned unit.

Choose a Gridfinity floor to use the bins you already print, or a smooth floor for things that do not suit a grid. Either way, the drawers are made to your dimensions.

Filament Spool Stand

Let the spool spin.

Rather than resting on a bar, the spool is gripped between two threaded cones that pull it true on its own hub — a 250 g sample or a wide 2 kg reel, any hub from 41 to 66 mm.

The spindle drops into open slots and gives line the moment it is asked. It stands level with our Filament Winder

FROM $3.00

Filament Winder

Filament goes where you put it, at the pace your hand sets.

The spool sits between two threaded cones on a spindle carried at both ends, so it runs balanced and true. The crank drives it through a printed gear train whose ratio you pick when you order — from 1:1 for feel, up to 2:1 for speed.

The spindle lifts straight out of its open slots, so changing spools is simple and easy.

Plate Rack Stand for CoreXY Printers

A stand that lifts your printer and racks your build plates underneath — dimensioned to your exact machine.

Swapping plates mid-session usually means leaning a warm sheet against the wall. Here they lie flat in slots below the printer — separated, cooling, one hand away.

Your printer stands on the frame, and the racking occupies the volume its legs already claim, so it costs you no bench at all. Slot spacing follows your machine’s measurements, and the parts are generated to print on the very bed they end up beneath.

$5.00

Modular Monitor Stand

Lifts your monitor to eye level and gives you a bank of flat-bottomed or Gridfinity drawers underneath.

Most risers are a shelf on two legs. This is a row of modular drawer units carrying a solid deck, so the dead space beneath your screen holds pens, cables, SD cards and hex keys instead of dust.

A 34” widescreen wants around 810 mm and no bed prints a part that long — but three units span it with no joint under the load. Our free bins fit if you choose the Gridfinity drawer style.

FROM $6.00

Parametric Filament Spool

A sturdy screw-together spool for re-winding filament — free, in three sizes.

Cardboard sags, cracks, and sheds dust into your feed path; refills and sample coils arrive with no spool at all. Print a rigid one instead — wind onto the hub, screw the two halves shut over the coil, and it drops onto any holder you own.

A single 55 mm bore serves all three sizes, so a 250 g sample and a 2 kg reel run on the same rod. Both halves print flange-down, unsupported. Free.

Add your printer

We size every model to your printer, so we need to know how big it can print. It’ll be saved for the next person with the same machine.

These are the printable sizes — the biggest part your printer can actually make, the numbers your slicer shows as the build volume. Not the bed or the removable plate, which are usually a little bigger.

Optional — build plate and printer-stand measurements

The build plate is the removable sheet you pop prints off; it’s usually a little bigger than the printable area. A plate rack is cut to the sheet, not the bed.

A printer stand is built around your printer’s feet. Give us all four and we can build you one — or skip them and add them later. Measure the BASE — the slab it stands on — not the machine’s widest point. Gantry legs, Z columns and X arms usually overhang the base and hold up nothing.

Where to measure your printer's feet Looking down on the printer's base with the front at the bottom. A is the full width of the base across the front. B is the diameter of one foot. C is from the base's front edge back to the center of the front foot. D is from the base's side edge in to that same center. FRONT rear feet — not needed A D C B
Looking down on the base, front at the bottom.

Choose your colors

Every model on the site opens in these three. Primary is the largest surface, secondary the part that contrasts with it, and tertiary the accent — feet, trim, the parts that tie it together.
