When doing retraction with the Ultimaker the quick connect on the extruder allows quite a bit of play.

This shim fits on the quick connect and essentially eliminates this play.

This thing was created using the Object Oriented Mechanics Library (OOML). See iearobotics.com/oomlwiki/doku.php?id=start for details.

This is a set of tile trays for the board game Small World that replaces the tray included with the game.

I found that with the included tray you had to split up certain races (skeletons) and either split up several other races or have their tiles sticking up above the lip of the tray.

The slots in these trays are specifically sized to the number of tiles for each race.

The set of three trays also take up less space in the box and are more robust.

This is a thing I made to experiment with different temp/cooling/fan settings on my machine in an attempt to improve prints that come up to a point or other small area.

I have Mac/iPhone power cords hanging around my bed, and I wanted a way to keep them accessible.

This holder goes over my headboard and holds my cords nicely.

The design is parametized, so it should be easy to adapt to any similar sized cord (or to fit over a different sized object).

This is my printable replacement for the stock reel holder that handles reels with smaller hole diameters.

I bought several batches of PLA which came on reels with ~37mm diameter openings. They don't fit on the stock holder, but they fit on this one quite nicely.

The STLs I uploaded will fit reels up to ~6.5cm wide and down to a ~37mm diameter hole. You can easily modify the length to handle wider reels via the OpenSCAD file.

Version 2 (V2 files) has a slightly wider gap between the tongues that fit onto the Ultimaker in order to address the issue encountered by Owen. I haven't tried printing the new version, so if you do please let me know how it turns out. If I get confirmation it fixes the issue I will delete the old version.
