Mini Utility Knife Blade Holder

thingiverse

This is a tiny fast blade holder for the small utility knife blades - more robust than an exacto, but not as bulky as a stanley blade. Only takes 7 minutes to print - it holds the blade firmly and has a blade retainer. Its a trial printing with PLA - it has quite a long 'bridge' and a 'spring' retainer - having got the dimensions sussed, I'll use the same structure for holding these blades in other projects. Print Settings Printer: Reprap Prusa i3 2017 model (from kit) Rafts: No Supports: No Notes: I printed it with PLA, it has a long bridge, with no support and needs tweaking once complete. NOTE Print with the retainer side down - so the big flat side is done last, bridging the whole blade slot. Post-Printing Cleaning If the bridge over the void has held, nothing needs doing. But... The void for the blade is likely to need a bit of 'separating' if the bridge hasn't held up. Just slipping the blade in and wiggling a bit works fine - careful separating the 'retention' blob - cut it off and the blade may not stay put. I found levering it was better than trying to cut it free. How I Designed This I measured the blade and tweaked through 5 prints!
