17.1.2021:
I added large brim inside of the tall middle models so you do not need to add any brim in slicer. It makes brim from outside, which is hard to remove. internal brim is much easier to remove.
I tried to find good thing and I found one, but it requires support. So I was forced to remake it so you do not need any support at all. Another warning was about fist capsule put in there, because when it fall wrong oriented, it can fall out from holder. Only what I like, it is labeling system.
This is original idea:

If you use bottom, 3x middle and both tops, then it is exactly for 16 capsules which is content of one paper box in shop.
I printed it in 2 perimeters, 20% infill.
It is not stackable, so you can screw it on some nice wooden or plastic pad, countersink holes are there.
I removed both disadvantages of original design. there is no support needed and there is closed profile at bottom, so no way capsule can fall out from holder.
I put there also step files and my original SolidWorks files if someone wants to change something...
