Tamiya Paint Storage Spool

Inspired by the many filament spool storage ideas on Thingiverse, I present the storage spool for large Tamiya paint bottles. This is designed to use MakerGeeks filament spools, but if your spools are 8" OD and around 2" ID, it should work. These can be stacked on a piece of 1 1/2" diameter plastic pipe. To do that, you'll have to make a disc of some rigid material (I used thin plywood) and attach to the bottom end of the pipe with a couple of angle brackets.
Print 5 of the "Tamiya spool" files for each layer you want. The "Spool Shim" parts are to shim the inner diameter of the spool to the 1.5" plastic pipe. The "spool disc" parts are stacked between the spools to make them spin better.
