These allen key handles (2.5mm - 6mm) attach to the end of your allen keys to provide better grip and more torque. Optional spinning cap on the end allows you to screw while keeping pressure on the key.

Allen Key Handles

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.

Saw that LTT released a 3d model of a holder for their screwdriver to use with their MCM power bar. I have a Wall Control pegboard, figured i would remix to work with an off the shelf magnet. Didn't work, it would just slide down as soon as i put the screwdriver in it. Changed gears to make it mount to the standard pegboard holes. It fits a little loose but it does work. I'm not sure how to tune it to fit tight against the pegboard, but since this still does the trick I decided to publish it.

Printed with a 0.6 nozzle at .18 layer height. 
Supports enabled, type normal - snug 
Outer brim only enabled. At 15mm, brim helps keep the supports down.

Re-slice for your nozzle size, but keep use the modified settings.
