CR-10 Magnetic Bed Kit

thingiverse

These are some parts I designed for upgrading the CR-10 to have quick swapable steel build plates, held in place by magnets. I made three of the plates from a 1m by 0.5m sheet of 0.5mm steel. The idea is to print one part and then immediately switch to the next without waiting for the bed to cool down - simply pull off the old plate, slap on the new one, and keep printing. Once you remove the build plate, it cools relatively quickly, allowing you to easily lift out your finished part by flexing the steel sheet. This setup eliminates the need for those pesky binder clips that always seem to get in the way. Additional Parts: * 0.5mm thick steel plate measuring 310mm x 320mm * Eight Neodymium 32mm disc magnets (available on Amazon) * LokBuild Build Surface (or any other brand you prefer) The bracket attaches under the bed, holding the magnets securely without needing glue. Be aware that due to its thickness, it will compress your springs noticeably - I personally like this as it makes the bed feel more solid. However, depending on your hot end's design and mounting system, it may make using a glass bed more challenging, but it works perfectly for thinner steel sheet beds. The rim is a simple holder that secures the sheet when it's hot and just pushes onto one edge of the steel plate. I printed both parts in PETG. While ABS would likely work well too, I'm not sure how PLA would hold up over time, so I'd probably avoid using it personally - but ultimately, it's your call.
