This is an upgraded version of my Modular Can Stacker. https://www.thingiverse.com/thing:2063580
The slide pieces have been rounded on the edges and the tolerances have been adjusted so that they assemble and separate much easier.
These can be connected to extend them to store as many cans per row as you need.
The parts marked "Modular can base" are flat on one side and are for the bottom row.
The parts marked "Modular can center" are wavy on both sides and designed to go between rows.
I have printed in PLA and ABS with no issues.
No special post-printing work is required in most cases.
The first connection may be a bit tight but afterwards, they come apart fairly easily while staying together quite well too.
