Gridfinity Bins

Gridfinity bins! Gridfinity bins! Get yer Grinfinity bins here! Print as many as you need to fill your drawers and stands or other Gridfinity projects.

The bins that fill everything else. Set a footprint in 42 mm cells and a height in 7 mm units, then download it — free, as many as you like, whenever a drawer needs one more.

They sit on the standard grid, so they suit our drawer systems, our stands, and any Gridfinity you already print. Ask for one bigger than the build plate for your printer and it's created in snap-together sections instead of refusing.

Laptop/Tablet Stand

An inclined riser tuned to your laptop and your desk.

Raise the screen to where your neck stops complaining. You pick the footprint, the recline, and the bar stock every member is generated from, so the proportions answer to your desk rather than to an average one.

It breaks into four parts that snap together and lie flat on the plate. Printed support-free, which means no scarring across the faces you actually look at and nothing to clean up before it goes together.

FREE

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.

Fits-Anything Clamshell Case

A case for anything. Seriously. Anything.

Measure what you want to keep, not the box. Give it an inside length, width and depth and every part rebuilds around those numbers — the hinge grows with the case, so a floss-pick tin and a caliper case are the same design at two sizes rather than two designs.

The hinge prints closed, in place, already hinged. No pin to push, no knuckles to thread, nothing to glue. It lifts off the plate working, and clips into the base and lid on barbed connectors.

Decide how the depth splits: an even clamshell that opens like a book, or a shallow lid on a deep tray when the contents only want one side. A sprung catch holds it shut, and a thumb relief in the rim flicks it open.

FREE

Vertical Laptop Stand

A vertical stand built from your laptop's own measurements — not a size that nearly fits.

Most vertical stands come in small, medium and large, which means yours either rattles in the slot or has to be forced into it. This one is cut for the machine it holds: type in the three measurements and every dimension of the stand is derived from them.

Three clip together parts, no screws, no glue.

Free. Configure it, turn it round in 3D, and download it.

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.
