Simple Interlocking Spool Holder

i didn't need a spool holder to print from or anything, simply to store my spools in my bin and keep them organized. i couldn't find a design i liked so i made this as my first 3d modeling project. i thought i would share in case someone else finds it helpful :)

these will fit spools up to 70mm wide, and they interlock to one another to help keep them organized

this design is HEAVILY inspired from a different one i printed over a year ago and i cannot for the life of me find the original post. i don't think it was on thingiverse but if you happen to come across it please let me know so i can link it! i liked the design but it was slightly too small for my spools so i decided to recreate it and alter it a bit to my liking
