I posted this on another forum, but figured there might be some interest here as well. So the latest round of Snowmageddon 2019 shut down the town and closed work today, giving me the perfect chance to finish designing a wrench to fit my Obsidian 45. I drew up a basic hex wrench for swapping my Liberty Sovereign mounts a while ago and wanted to do something similar for my Obsidian, but I also wanted to include an end cap wrench, regular mount wrench and 3-lug mount wrench all in the same tool. Here's what I came up with: It's about 6.5" long, is pretty comfortable to use and prints without supports. Took a few iterations to get the fit right, but all three wenches interface very well with my Obsidian. I've never posted a design up on Thingiverse before but I'll be putting this one up once I figure it out in case anyone is interested.
