F.A.R.T. Wrench
thingiverse
Did a quick draw up on a wrench for the Frankford Arsenal Rotary Tumbler end cap. This should have a snug fit and give better hold when opening and closing the end caps. I designed it to be 1" thick but could easily be thinned out to ~3/4" to save on filament and print time. I sliced it with Cura with 45% cubic subdivision infill and 6 layer walls all around.
