Inspired by the Triple G Workshop's Cube Background Panels and Eusterics' idea of making it self assembling I made a version with magnets (6x3mm) which is easy to print, assemble and store.

I designed it from scratch, but I think it's a kind of remix.

There is also a blank panel which can be used to fix LED strips for bright light (last photo).
Please turn a blind eye to my soldering skills.

Printing & Scaling

You need 3-5 panels and optional the top LED panel if you want to use LED strips. Otherwise you need some strong light sources.

No supports needed. I used PLA Marble with .2 layer height, which looks great.

I recommend using the test print to check if your magnets fit in the holes.

Each panel has dimensions of 225x225mm.

You may also scale it down to 66,667%, so the dimensions are 150x150mm, which is printable on a Prusa mini or Bambu Lab A1 mini. You would need 4x2 magnets.

If you have a bigger printer you may also scale the parts up to 133.333% (=300x300mm) and use 8x4 (or two 8x2) magnets.

Use the STEP file if you need other (magnet) dimensions.

Assembly

Take care of the right polarity of the magnets!

Each panel needs 4 magnets 6x3 per side. This means up to 16 magnets per panel, depending on how flexible you want to be.

I always inserted them from the right side and used the north polarity for the two top magnets and south for the two bottom magnets.

The holes for the magnets have a diameter of 6.1mm for a snug fit. Depending on how good your printer is calibrated I recommend using super glue to fix the magnets.

Now you have the perfect background for photos of your 3D prints!
I would love to see them …
