Since I was unable to use all of the endcaps in the 10" Pegasus 8mm ACME Leadscrew Z-axis upgrade for my MakerFarm 12" Pegasus, I decided to print an extended version. Instead of having only 7mm of room for a T-Nut, you now have 17.
Everything else is to the endcap's OEM specs, besides the V-Rail geometry. That is based off my V-Rail extrusion 2D profile. Enjoy!
