So I got the LTT Screwdriver at launch and I love it but I wanted to add a bit more grip. So since I had recently purchased my first 3D printer I decided to try my had at doing some TPU prints and thought this was perfect. I got the mock up model and made it ever so slightly bigger and then subtracted the selector ring and knob. I then printed it with PolyMaker TPU in vase mode and it turned out decently and wasn't really too hard to put on. This won't take a lot of effort to remove afterwards but it works well enough that it won't just come off on it's own.
