Compact filament multi spool holder

thingiverse

I replaced my "prusa style" spool holder design with this new one. The features include: * Much reduced roll friction compared to eg "prusa style holders". No bearings are needed. Filaments can be loaded and unloaded very easily, just lift the spool. Any number of spools can be added in parallel (I use 2 times 3 spools as shown). Low-material cost and easy-print design make this a great option. The compact, interleaved design saves space. Re-use of Prusa's metal rods is possible. If you don't have them, why not print them instead? This design is compatible with 3d TOPS 49-mm spool diameter. It's even possible to put the entire setup inside a box or air-tight compartment (see picture). Simply print the .3mf file a few times (you might want to remove items for later prints as some parts are only needed for every second spool). Alternatively, you can use the STLs directly (remember to alternate between the "left" and "right" style sides as the axis will be placed in an interleaved manner to save space). You'll also need to print a "filamentrullepuck.stl" for each filament roll. If the spools are loose on the metal axis, just add a small piece of thin tape before inserting it. If needed, simply change settings in the spreadsheet within the FreeCAD document and re-save the STLs. If you don't have Prusa's metal axis available, just print a 120mm rod or split into two 60mm parts for easy printing. Enjoy!
