About this model

Support legs for stacking specific racks of small-gauge hook-up wire spools for electronics. I really like the "Modular Wire Spool Holder" by Sisul, and the remix "Spool holder box" by Azuzula. These spool holders are for small electronic hook-up wire, which normally come on plastic spools about 55mm in diameter, and 20mm wide (like and similar). However, stacking these racks reliably can be difficult, especially with Azuzula's simplified remix design (and this is the one I used for my racks). These simple legs provide solid stacking of either of these modular wire spool holder racks. Though I used Azuzula's design for my racks, I took the exact dimensions from Sisul's FreeCAD design files, so they should work fine with either implementation. A possible bonus of these legs is that a single…
