Lack table joiner and raiser & 3D Printer cabinet

I was building a 3d printer cabinet and wanted to use two lack tabes for it. But the printer did not fit, so i needed to raise them. I added Plexiglas windows with magnets, and wanted them to attach properly, so i printed some strips (leiste, which i also included)

you can take the top table any time you need as it is only plugged in. the raisers are screwed against the lower one.
