3D printer accessories

Stackable, rackable, no supports or extra hardware, sizes much wider than your printer, leveling feet, cross-ties for support even caps for the unused rod holes. It's safe to say we went over the top on this one!

The rods tightens like a turnbuckle. Threaded pegs screw into each side plate, and every rod has a left-hand thread at one end and a right-hand thread at the other. Wind a rod on and it draws both plates in together, until both ends seat on the same turn. A cross-tie across the back keeps the bay square, caps close off the outside ends, and stacking clips lock one rack on top of another. Every part is printed — there is no hardware to buy.

It stands on leveling feet that cup the bottom of each plate; turn a knob to take up an uneven floor. Your files come plated for your printer, with the rods sized to your bed — on a smaller bed they print shorter, and short threaded extensions make up the width. Pick your colors, preview the rack in 3D, and see exactly what you will print before you buy.

If there's anything we didn’t think of, let us know!

Filament arrives on the wrong reel. Tangles want rewinding under tension, 2 kg rolls want halving before they will sit in a dry box, and an orphaned end deserves a smaller spool rather than the bin.

Crank it. Pick gearing anywhere from 1:1 to 2:1 — quick and firm, or slow and kind to your wrist — and the handle relocates to suit. The spindle lifts out of an open channel, so swapping reels takes seconds.

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

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.

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.
