Corne (crkbd) split keyboard thick plates

thingiverse

UPD: 24.01.2021 Added a "no-rubber-feet" version for the backplate by request. This is a set of two plates designed specifically for the Corne keyboard created by foostan on GitHub (https://github.com/foostan/crkbd). To minimize flex, I've made the midplate significantly thicker at 4.5mm instead of its original 1.5mm thickness. Cherry MX-style switches can still be clicked into place because I left a small lip for them to latch onto. On the photo, you'll see that 6mm M2 stands and 6mm M2 90-degree countersunk screws are being used. There are also designated areas for attaching 10x10mm rubber feet on each side of the plates. The files provided can be mirrored in a slicer to create a set of plates for the other hand. Since the lip on the midplate is crucial, it should be printed with the lip facing down onto the build plate. This will ensure that the side with the lip ends up facing the keycaps, allowing the switches to click into place properly. The step-files were exported from KOMPAS3D using AP242, but I'm not sure how well they'll export. If you encounter any issues with the files, please let me know. To achieve optimal results, I recommend printing the midplate with 100% infill for maximum rigidity. The bottom plate's infill shouldn't be as critical, so I used 20%. Printing at least two perimeters should yield good results, but feel free to experiment and find the perfect settings for your printer. I printed these plates on my Ender3 Pro using Russian-made PETG, but PLA should also work just fine.
