Wiha Precision Handle With Rotating Cap

Description

Alright, something for your toolbox. First I would like to say that I'm in love with my Wiha precision screwdrivers. They are elegant, they are awesome, they are tough as nails and thanks to the rotating cap on the end, you have very precise single-handed control. Anyway, I recently got a new set of cheap diamond files, which were not bad, but handles were total crap. I wanted something more substantial, more elegant, more precise, more ... Wiha. Here are some of the features I wanted from the precision handle: 1) Freely spinning cap on top of the handle to you can push the cap against your palm and use fingers to twist the handle freely. 2) Handle and cap must be printed separately. I want to use different color caps to color code my tools. 3) Cap is press-fitted to the handle, there are no fasteners needed. 4) You can (lightly) hammer the top of the handle. Yes, it is a precision handle, I know. Still, I want to be able to hit it! 5) Wiha looks (looks are so important ;-) So here you have it. …………………… The handle is designed in OpenSCAD for extrusion width 0.5 mm and layer height 0.2 mm. This is a very thin and tall model, it is crucial to NOT have gaps between shells. So if you are using different slicing settings, I recommend regenerating the handle with your values from the SCAD file. Since you are going to be press-fitting your tools into the handle, I only recommend PETG and print about 5C hotter than usual to give it more strength. I would also recommend to clean up the hole with a drill bit before press-fitting. I was printing my handles with something like this: 250C, 6 top & bottom layers, 4 shells, 50% infill, allow single extrusion fill and print at 30mm/sec. Go SLOW if you want to nice-looking handle! I used a vise with two blocks of pine as jaws to squeeze the needle file without marring it and then I hammered the handle on using a wooden mallet. …………………… The source file is included. If you remix, you must share your source file. …………………… Note: Generated ZIP file is borked (thanks Thingiverse!) so it is better to download individual files.
