Eraser holder and straight edge

thingiverse

I have a hard time drawing a straight line myself, and I end up erasing a lot while drafting. That's where this handy tool comes in to save the day! It has everything you need for 4'' line drawing and erasing needs covered. The device holds a standard poly eraser that you can easily find at any school or hobby store. The design is sleek and features a fold-out straight edge, perfect for making accurate lines. There's also a spacer that keeps the eraser elevated as it wears down over time. This means you'll never have to worry about your lines getting wonky because of a wobbly eraser! To assemble this nifty gadget, start by printing it out on a Rep2 3D printer using medium quality settings with 10% infill and no support material or raft. Once it's printed, take a small piece of sandpaper and gently smooth out the edges. Next, place the spacer inside before inserting the eraser. This will ensure a tight fit that keeps everything in place. To make the process easier, wet the eraser slightly and then push it into position. Let it dry completely before use. With these simple steps, you'll have your very own line-drawing tool in no time!
