Parametric Wire Spool Holder

Simple, parametric wire spool holder for common small spools (AliExpress / Amazon types like Fermerry 20AWG sets). Instead of keeping wires in flimsy boxes or loose on rods, this design stores each spool in a compact box with an internal core so the spool can rotate freely while feeding wire. The side opening allows smooth dispensing and a quick way to secure the wire end. What’s different from the original This is a full redesign based on the idea from HakiP’s modular spool holder: No screws required Strong snap-fit assembly (tested in PLA, PETG, ABS) Fully parametric design (Fusion 360) Adjustable to fit different spool sizes Enter your spool dimensions and generate a perfectly fitting box. Key Features Snap-fit closure — no hardware needed Fully parametric — adapts to different spool sizes Internal rotating core Wire exit slot with retention Stackable / modular concept Clean print — no supports needed Printing Layer height: 0.2 mm Perimeters: 2 ( Tested ) If you Use 4 Top/Bottom the
