ISIS BB tool

This a seriously ugly design but it worked so I stopped refining it.  I printed in both PLA and PETG and the PLA worked better despite the 3mf still being set for generic PETG (choose your own adventure). This was only tested removing an old ISIS BB as I didn't want to wait for a cheap on to ship. I had to reinforce the model with 8 M4x30 screws (longest I had on hand or I was considering using heat set inserts inside the socket well, add them if you want).  I used a Bessey clamp to turn it, backed up by a strap wrench as shown in the picture.  I don't think the strap wrench was needed but it made me feel better as the bar of the clamp was bending CONSIDERABLY because I had to rotate to prevent layer lines from splitting.
