Multi-Frame for wall, Multiboard, Kallax backwall

I have the Kallax door from "pjp." revised so that I can use this as a back wall for my freestanding Kallax shelf... as you can see in the pictures, I have my folders on one side, and now a work of art on the other side :-)If you want to make your own insert, you must use the following dimensions: 236 x 236 x 2.5-2.8mm.I added an attachment for the wall to the frame, so you can also hang the frame on the wall, and with the "Multiconnect" you can also hang it on the multiboard.

A division into 4 equal parts makes it possible to print the frame horizontally, which now gives it the finish of the print bed. In addition, by cleverly arranging the Purge Tower, I was also able to print and insert Hueforge image in full size. Now I'm looking for a way to make the magnets unnecessary. you need got V1:4x M3 inserts4x M3x8 FHCS (flat head) to connect door panel halves ich habe die Kallax Türe vo
