Cartridge storage - Genesis/MegaDrive/MasterSystem

UPDATED - VERSION 2
After printing a set I found I'd left way too much play in the spacing. The slots were too large and there was enough wasted space in the 1x4 to fit an entire additional cart. So... version 2.

If you've already downloaded and printed one, I left the previous versions as a zip file in case you need to print one again in future. But please note, they are NOT compatible with version 2.
UPDATE UPDATE: I added an additional top which has a lip to cover the join in front.

These stackable storage shelves will fit Genesis/Mega Drive and Master System cartridges.

There is a 1x5, 1x2, and 1x1 version. They're all the same width, so you can mix and match if you want. There's also an optional base and top if you want a nice finished look.

The tolerances on the feet/connector aren't super-tight, so they should fit together fine (with just a little coaxing and maybe some sanding on the edges of the 'feet'.)
