220*220 Magnetic Bed mod

thingiverse

These parts are for a 220*220 heated bed. In my case a anet a8. I bought some spring steel with PEI sheets. From here, aliexpress link https://bit.ly/2C3xGWz with some 24x14x3 n52 magnets. link https://bit.ly/2RxJD0s I didn't find exactly what i was looking for on thingiverse, so i made it! The corner edges go high enough to keep the plate centered, the magnets will hold it down. The rear holder has built in strain relief for the wires, Mine still hang down from the top so it was designed for that. I took inspiration from https://www.thingiverse.com/thing:2066067 The spring holes have a sacrificial layer for the m3 screw. you just need to drill it out, but no supports needed for that. the rear piece has a honeycomb pattern to save material and lighten the part. with a solid bottom layer for print adhesion. I printed this with ABS so it is designed with that in mind, I've attached the f3d files if you need to remix it for yourself with some other material in mind.
