Sitivian ST-102 Knife Back Spacer / Back Strap

prusaprinters

This print is to make the Sitivian ST-102 flip knife much safer. This knife stock comes without any back spacer so when folded closed the blade can be easily touched through the gap between the handle. Even if you don't have thinner fingers, just a small amount of pressure could push your finger/thumb deep enough to get sliced. So I designed this backspacer to make that impossible.The print is very quick to print and it snaps on to the bottom of the knife. When you get it snapped on, it might tilt slightly out but just push the top part into the gap and it will stay. It's not perfect but it fits well and hasn't broken or popped off for me after months of use, while keeping my digits fully intact. With this, you can reach into your pocket and really squeeze the knife without any fear of accidental cuts. Installation: It just snaps on but it's probably easiest/best to start with the bottom hook area, then sort of pull/stretch/flex the middle prong around the back to get over the hump. I tried it the other way at first and it broke the middle prong since it's less robust than the bottom one. I printed this with:Ender 3 v2100% infill.4mm nozzleTecbears black PLA200 deg C nozzle60 deg C bed no supports
