Adjustable anti wobble z coupler

thingiverse

Surely not the first of similar ideas, but i couldn't find one that had 3 point support to allow fine adjusting the alignment and was small enough. This is the same size as the standard aluminium coupling (20x20x25mm), apart from the screws sticking out a bit. Needs 3 short m3 screws with nuts for the top, 2 longer ones with nuts for the bottom half, i simply used leftover ones from the printer. Printed with 3 outer layers, no infill, and no supports.
