3D Printer Spool Roller Is Built For Giant Spools Of Filament

Most 3D printers come with a pretty basic filament holder — often little more than a bar to hang the spool on. [Ivan Miranda]’s 3D printers run bigger spools than most, though, so he had to craft an altogether more serious solution.

Unlike most of [Ivan]’s creations, the spool holder isn’t actually 3D printed. For this job, he turned to a laser cutter instead, cutting the parts out of 5 mm plywood. A handful of layers of wood bolt together to form the frame. The frame holds several bearings for the outer rims of the spool itself to ride on, allowing it to spin freely as the extruder tugs on the filament. Reducing the rolling resistance of the spool is key when working with such large, heavy spools, and reduces the chances of the filament not feeding properly.

It’s a tidy example of a tool built quickly and easily using a laser cutter. It pays to remember that while 3D printers are great, a laser cutter can often turn out parts in a short fraction of the time.

3D Print Spool Holder

Ingenious Filament Spool Holder Keeps Your 3D Printer Printing

If you have a 3D printer, chances are, the company you bought it from skimped out on the design of their filament holder. It’s okay though, it’s not like having a toilet roll holder for your spool will result in failed prints… oh wait…

We don’t normally share projects like this because, gasp, it’s not really a hack, but this completely 3D printed filament spool holder by [Creative Tools] is actually quite amazing. It’s been designed to fit pretty much any kind of spool of filament you can imagine, as well as no spool at all. But what impresses us most is how the entire thing is 3D printed or makes use of 3D printer filament. No fasteners, no nothing.

Stuff like using rubber filament instead of grippy foot pads, and hard filament as the axles with 3D printed wheels for the quasi-thrust bearing used to support and rotate the spool.

All the parts are available over at Thingiverse.com — even if you don’t have a 3D printer, you might want to see the following video for some inspiring design tips on how to make such a clean and polished 3D printed assembly.

Awww Shoot! My Spool Doesn’t Fit My Holder


The great thing about standards is that there are so many to choose from. Filament spools certainly do not deviate far from this sarcastic saying. So what are we 3D Printer folks to do? Here are a couple completely different DIY options:

[Mark] made a spool holder that can accept 2 different width spools. This design uses skate bearings to support the spool on two points at each end. There are 3 sets of bearing blocks to accommodate the 2 different width spools. When either size spool is installed, one of the bearing block sets goes unused.
