Stackable Wire Spools

There are three different sizes of spools 10,20 and 50mm tall. Two 50mm spools back to back hold 100M of 16x0.2mmSq (330ft of 20AWG). The stack of 10mm spools i have made would probably take 10M of 16x0.2mmSq (33ft of 20AWG). I have made them for myself to hold 10M of 7.02mmSq (33ft of 24AWG), which only takes up about 2/3rds of capacity.

A 50mm and a 10mm spool take 100M of 7.02mm (330ft of 24AWG). These are the three sizes that the spools were designed for. They are made push fit without the need for glue, at least while they are new. The main thing is that i can put 10M of cable of different colours each of the smaller reels without taking up a lot of work space.
