Simple linking boxes

I needed some small containers to hold rings, earrings and other jewellery that could be printed easily on a MPMD. Most boxes I found were more complicated than I needed so I designed these. The boxes are open and can be used individually but are meant to be linked together. I opted for small retaining clips rather than altering the box itself. I intended them to be linked and placed inside a larger box but these can be used on their own.
Each box is 50mm x 50mm x 20mm divided with a low separator (about 8mm) into 4 sections.

I printed at 0.28 and 100% infill, but use what works for you.

Full clips for inside corners and 1/2 clips for outside edges.

Edit:
1. Added a 10mm high version in case anyone needed a lower box
2. Added a stackable box (it fits over the clips) if you want to pile sets of boxes. This can be printed in place of the regular box.
