This was designed around a Wheels Mfg Threaded-in PF30 bottom bracket. You need 2 tools to tighten it in and I did not feel like buying another Park BBT-29 tool. I used the park tool to torque down and this tool to hold the other side. I added (4) 3mm x 18mm pins I got off Amazon but I think for how i used it, all plastic would have worked. I do not know if it is strong enough for 35-50nm of torque.
Its a tight fit in Petg, in my experience PLA shrinks a bit more so best to print it upside down for a couple of millimeters and check fit. Scale up as needed. I included a deeper version for those who would want to use it on a Mega BB, it a totally untested design.
