QIDI X-Plus roller bearing holder

thingiverse

I really like this design. It is a simple way to get filament rolls to turn easy on the QIDI X-Plus. I had problems with the original piece that holds the bearings. They seemed a little thin and I couldn't slide the QIDI spool support rings over them either because it's a bigger than the aluminum tube diameter. I couldn't get my bearings to insert, they printed too small for the bearing OD. Here is what I changed in this design: Added a little more thickness to the outer lip Reduced the OD to just under 30 mm so the QIDI spool rings can slide over these Made it deeper and added a lip inside to seat the 7mm wide bearing Added another 2mm of depth in the center to prevent the pin from possible rubbing Made the bearing hole diameter 22.10mm for better bearing insertion FYI I printed the pins at 100% infill because they broke on me a few times at 50% (might have been the filament I was using).
