Crank Handle for Fully Printable PCB Vise

thingiverse

Rewrite the given text as a revised version with improvements. Keep it concise and informative, explaining the modifications made to the PCB vise design and detailing the printing process. Mention any tips for assembly and adjustment. Additionally, highlight the ambidextrous nature of the handle. In this updated version (V.3), Sneakypoo's Fully Printable PCB Vise features a 3-way split shaft, reducing stress during insertion, and it comes with a matching shaft. For V.2, the knob shaft has been rounded and protrudes less for a cleaner fit. To print, use Autodesk 123D Design and set parameters at 4 shells, 15% fill, .3mm layer height in Makerware on a Replicator 2. If lock tabs break when inserting the knob, print it at 98% x/y (keep 100% z-height). Preheat the shaft with a blow-dryer for easier insertion. Ensure the knob protrudes opposite the + shaped key that mounts to the screw. It may require about twenty turns to loosen, but it should turn freely after that. For stability, stuff scrap plastic between the split pieces and apply a tiny drop of super glue (avoid gluing the knob). The handle design is ambidextrous, so choose left- or right-handed installation as desired.
