220*220 Magnetic Bed mod

thingiverse

These parts are designed specifically for a 220x220 heated bed. In my case, an Anet A8.\r\n\r\nI purchased spring steel along with PEI sheets. Here's the link from Aliexpress: https://bit.ly/2C3xGWz\r\n\r\nAdditionally, I acquired 24x14x3 N52 magnets. The link for these is: https://bit.ly/2RxJD0s\r\n\r\nAfter searching Thingiverse, I couldn't find exactly what I needed, so I created it from scratch!\r\n\r\nThe corner edges are designed to be high enough to keep the plate centered at all times, while the magnets will securely hold it down. The rear holder features built-in strain relief for the wires. Since mine still hang from the top, it was designed with that in mind.\r\n\r\nI drew inspiration from Thingiverse's 2066067 design.\r\n\r\nThe spring holes have a sacrificial layer for M3 screws. Simply drill out this layer, but no supports are required for this process. The rear piece has a honeycomb pattern to minimize material usage and lighten the part while maintaining a solid bottom layer for print adhesion.\r\n\r\nThis design was specifically created with ABS in mind, so I've attached the F3D files if you need to remix it for use with another material.
