The spool holder fits all spool sizes from 10 to 90 mm in width. It takes standard skateboard bearings (22x8x7 mm), and only two M3 nuts and two M3x10 screws to assemble.
It is designed to be resized fast and easily and be as compact as possible for transport.
Order of operations to get everything together (See picture for orientation):
1. Push Beam2 through the inner right part and push Beam1 through the inner left part.
2. Put the two parts together by threading the beams into the hole on the opposite part, also make sure the pin in the middle of Beam1 goes into the hole in the middle of Beam2.
3. Add the Bearings.
4. Clip on the two outer parts, you won't need glue since the press-fit should be somewhat tight, and the parts will be secured by the screws. To add the screws, first add the nuts from the bottom, and then screw the screws in from the top until they grab the nut. (DO NOT TIGHTEN THE SCREWS TO MUCH! This will clamp the beams down and you won't be able to move them.)
Update: Changed the screw head hole size from 5.1mm to 5.5mm to fit all screws.
