Thread Spool organizer for Storex 12x12 Project Box

thingiverse

I created this remix to fit inside of the Storex Project Boxes I bought on Amazon. I resized the spool holders to fit precisely inside the boxes, and modified the spacing of the spools a bit. The 36-spool holder has a C2C (Center to Center) spacing of 25mm. The 18-spool holder has a C2C spacing of 33mm.You can mix and match the 18- and 36-spool designs, but for each project box you will need 2 of the "A" designs (bottom left and top right) and 2 of the "B" designs (top left and bottom right). It was less than 3 hours to print each one on my Ender 3 Pro at the lowest resolution (0.28mm per layer). I used 5mm carbon fiber rods meant for model airplanes and drones as the pins to hold the spools. Vertical space inside each box is approximately 68mm, so I ended up cutting my pins at 52mm. I cut them on my bandsaw, and yielded 8 pins per 420mm rod. This gave me a price of $0.33 per rod. There are quite a few different lengths and quantities of 5mm rods available on the internet, ant varying price points.You could also use 5mm wood dowels if you can find them, or print your own pins to fit. The holes in the model are sized at 5.20mm, but my printer makes holes undersize by a bit in the first 4 layers or so. I found it helpful to ream out each hole carefully with a 13/64" drill bit which yields a hole size of 5.16mm. This is a good gap for the epoxy to fill in. I think super glue might work as well for this purpose but I have not tried it.
