Stage Lighting Focus Wrench Version 2

prusaprinters

This is a tool used for hanging and focusing theatrical/stage lighting fixtures (note - I'm based in the US.  This may not be as useful elsewhere).  It includes holes for each of the 3 most common sizes encountered on c-clamps; including the square pan bolt, square 5/8 bolt, and the hex ¾ bolt.  There are additional holes in the middle that work well with the wing nuts sometimes encountered on o-clamps.  All pointed holes have been made into multi-point (12 point on the ¾ bolt, 8 point on all others) to give a little more flexibility when working in tight spaces.  I've also found that the multi-point design tends to be much stronger than the original.The design is loosely based around a tool I carry on a regular basis, with some changes made to (hopefully) make it last longer as a 3d printed part.  I'd initially set out to design an inexpensive tool that I can had out to volunteers and not expect back at the end of the day, but these hold up surprisingly well, and I've found myself reaching for them more often than the original.I print them on my P1S in cheap PLA with the “0.2mm Strength” profile with no tweaks.  This breaks down to the following:Layer Height: 0.2mmWall Loops: 6Top Shell Layers: 5Bottom Shell Layers: 3Infill %: 25Infill Pattern: GridYour mileage may vary.  If you're having trouble, I've found that the wall loops is the most important aspect for strong wrenches.
