Prusa i3 Bed Adjustment Mods

thingiverse

I've used a couple of different versions on my Prusa i3 clone and custom printer with a print bed designed for Prusa. The inserts I used can be found at mcmaster.com, specifically the 94510A310 model. The 4-40 insert was what I could find at the local hardware store in flat head screw form, but since its dimensions are close enough to M3, it should fit just fine on a standard printer. If needed, you can always drill out the hole, which is exactly what I do anyway. For your convenience, I've oriented the models so they're print-ready. They were printed using ABS, but any higher heat material like PETG would work equally well.
