If you, like me, printed everything in the UMP 11/9 out of carbon fiber nylon, then the skin of your fingers is all cut up and calloused and probably full of microscopic shards of carbon fiber. Not good.
Designed this quick little TPU sleeve that slips right over the charging handle and makes it more comfortable to rack while sitting in your living room watching movies. You could glue it on but its snug enough to stay in place.
Print it out of the softest TPU you own and fenagle the settings to make it squishy. I used Ninjaflex.
