48.5 Bottom Bracket tool

thingiverse

This tool was designed specifically around a Wheels Mfg Threaded-in PF30 bottom bracket. Two tools are required to secure it in place, and I opted not to purchase another Park BBT-29 tool. Instead, I used the park tool to apply torque while holding the other side with this tool. To enhance its stability, I added (4) 3mm x 18mm pins sourced from Amazon; however, given my usage scenario, plastic alone would have sufficed. Its structural integrity under 35-50nm of torque remains uncertain. When printing in Petg, a tight fit is expected. Based on my experience with PLA, it tends to shrink slightly more, making it ideal to print the design upside down for approximately two millimeters and then check the fit. Scaling up as needed will ensure a proper fit. A deeper version has been included for those who plan to use it with a Mega BB; however, this design is entirely untested.
