Bracket for Moon Cerberus rear LED light on pannier rack

prusaprinters

<p>Moon Cerberus rear bike lights are very popular but they mount on the seat post and if you have a rear pannier it usually blocks the light from view. &nbsp;This two-part print will bolt to the two holes usually present on the back of most pannier racks, and provide a post for the light to securely clip to. It also cannot slip off downwards.</p><p>Print in the parts, and screw them together with two M3 x 15mm bolts. Up to 18mm is fine. 20mm will bottom out so don't do that. Bolt to your bike with M5x8 or M10x10 bolts, adding a washer if needed (the threaded holes are 6mm deep). &nbsp;In both cases the screw threads are printed in the model, no need for inserts or tapping.&nbsp;</p><p>I dont think layer height is important, I used 0.2mm for our two bikes. If you live in a hot climate consider using white PLA or even PETG so it doesn't melt but here in Wales black PLA is fine.</p><p>When printing, lay both parts flat in the obvious way. Turn off supports, there is a sacrificial layer to support the threaded holes in one part, so no supports needed.</p>
