Modular Wire Spool Holder

I have bought wire of the label Striveday. It was delivered in a strange cardboard box, which should also serve as a dispenser. Working with it was frustrating, the wires got tangled up all the time, untangling was almost impossible, because all spools had to be removed and put back in at the same time.
So I designed a spool holder with the following features:
- for reels with 20mm width, up to 60mm / 25.5mm diameter ('Striveday')
- Modular design, any number of units can be combined
- Reels individually exchangeable
- Wire is clamped in a V-shaped notch for fixation
- Can be glued together for assembly or screwed together with threaded rods
- .stl files available for an empty spool

The holder is made up of several parts and consists of two side parts and the required number of reel holders. You can either glue the parts together or screw them together with 3 correspondingly cut M3 threaded rods. The parts are aligned to each other with pins and the corresponding holders.
