Twin headshell box

So here it is, a remix of the nice headshell case. The design was completely remodeled in Fusion360 so now I can do any changes on it quickly :) It's outer dimensions remain the same, inside I changed these:

- lowered the shell holders by 3.5mm
- shortened them by 2mm so it's easier to insert longer shells
- increased the distance between them by 1mm
- changed the retaining blocks in the upper lid, made them lower and a bit wider to follow the changes made on the shell holders
- the cut under the latch was unnecessarily large, made it smaller (smaller through-print effect on the outer side as well!)
- changed the pattern on the upper lid where one opens the case
- applied fillet to ALL inside edges (some were missing in the original design) and changed to 1mm instead of 2mm which looked too much for me
- incorporated a little holder for a 45rpm puck
- under one of the holders I integrated a 52mm overhang gauge (for Technics players)

I think that's all. Hinge has the same
