I bought a heater to put in my 3D printer. To avoid making a hole in the cover, I preferred to design a riser to pass the cable through.

Please note that if you're printing on a P1S/P1P/X1C, you need to follow this tutorial to print on the whole tray: https://wiki.bambulab.com/en/knowledge-sharing/print-volume-limitations

Also beware of warping the part!
