Allen key ergonomic handle - multi size (metric)

prusaprinters

This is an universal handle for metric Allen Keys. It provides a better grip of the tool and allows to apply higher torque when screwing/unscrewing allen bolts. Inspired by design i found online, which was unfortunately paywalled, I decided to create my own version from the scratch.Fits wide range of allen key sizes (mm): 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10 Tool dimensions are good enough to be grabbed comfortably by adult hand. Snap-fit design so that each allen key stays in place when installed in its appropriate slot.I've tested the tool with several sets of Allen Keys from different brands and for most they should fit but the problematic part with allen keys is that there is no ISO/IEC standard for their bend radius and I've seen keys that don't even hold 90 degree angle. So with that there might be still some outliers won't snap in place. I might release later a version with even greater dimension tolerance.For print settings I've used Prusament PETG stock settings and infill of 15%. Can be printed without supports, small bridges and overhangs print easly on stock Prusa Mini although I recommend adding built plate supports so that the bottom part of the tool shell is printed nicely. 0.2mm layers is good enough, i recommend 0.12-0.15 for nicer look.
