Make use of vertical space by neatly attaching things to the poles of Elfa drawer racks!

A 3d printable clamp for mounting things to Elfa drawer poles. This slots in a M3x0.5 hex nut, and a screw can either be used to directly mount some object or as a keyhole stud.

REQUIRES EXTERNAL HARDWARE: M3x0.5 hex nuts. By default, this will lightly clamp onto the pole, but an additional screw (minimum ~10mm threaded length) and nut can be used to apply additional clamping force. A M3x0.5 nut lightly press-fits into the hole and both sides are identical (can take either a nut or screw head).

Designed for a rectangular cross-section of ~10x20mm. Should be usable for both the vertical and horizontal sections of Elfa drawer racks.

I typically print these in PETG for strength, and some flexibility is required for this to open up to clamp onto the pole. You can try PLA, though. Brim not needed. Examples printed on a Prusa Mini, 0.4mm nozzle, 0.2mm layer. If using PETG, make sure to set retraction settings for print quality.
