Drybox with indicator

So, I wanted to have a dry box for my spools.

This print requires some additional hardware. Specifically, I used skate bearings (22mm) to set the spool on, and some appropriate length M5 bolts and nuts to hold it all together. (Unfortunately, I do not have a complete list, as I was grabbing random bolts from my parts drawers until I found ones that fit)

Anyway. This drybox needs the following:

1 each of the bottom, middle, top and flag.

21 - 22mm bearings (10 each for the spool supports and 1 for the flag)

This will hold a 1kg spool no problem. The flag will give you a rough indication of how much is left on your spool.
