Pen Knife Grip and Safety Cap

thingiverse

I'm constantly on the lookout for a half dozen #1 Exacto knives, but it seems like all of them have one major flaw: their blades are loose. I'm convinced that the collet holder has expanded over time and can't pull the collet tight anymore. It would be great to design a better grip that won't roll off the table, and maybe even add a cap to keep it stored safely. This was a quick Fusion project, and so far, it seems to work well. However, I'm aware that the plastic may stretch over time, which could affect its ability to tighten down properly. They're quick to make, though, so that's a plus. I added a desk holder and a magnet mount to make things more convenient. Here's hoping someone finds this useful. Cheers, Kisssys
