Hobby Knife & Utility Knife

I created an X-Acto knife holder a few months back and have used it extensively. It's so versatile that another skilled maker in this house even swiped it from my workbench for sculpting! When I couldn't find it, I downloaded the STL file to print another, but it's barely large enough to fit within the printable area of my delta printer, so I wanted to create a slightly smaller version. These handles are designed from scratch, but they're a recreation of the original. Massive credit goes to CDugD for designing a clever mechanism to hold the blade in place! I incorporated that geometry and it works flawlessly. Some minor differences from the original design include: - A shorter length to accommodate smaller print beds - A greater front angle to expose more of the blade - A sharper curve behind the blade so you can grasp it closer - A thinner handle end, resembling a pencil in size - Chamfered handle edges for a smoother grip Additionally, there's a utility knife version with a large grip that you can pull on firmly. It's perfect for cutting cardboard or cloth. These designs require an M3x8mm screw and an M3 nut to hold the blade in place, just like the original. These designs are publicly available, so feel free to modify them as you see fit: https://cad.onshape.com/documents/5ab9c164b8de294653e560a6/w/4626239fce5bc14de377fbc4/e/b2a32978dcbe09e86022f8f6
