This was my prototype and may be my finished product. I will test it on my next few rides. Fits nice and tight on both the bike and the lock. I can clean up the openscad file and upload it if people want it.*Update* after fairly extensive testing, I have found that this model needs a little work to strengthen it, for PLA printing anyway. I think it would work great in ABS, but I have not tried printing ABS yet. I am still using my first set, but I will need to replace them soon
