3D printing pens may be toys to some, but they can be genuinely useful tools to repair 3D prints, rescue a support structure, or weld together different pieces. However, [BManx2000] found that the way the filament simply sticks out of the back of a 3D printing pen like a bizarre tailfeather was troublesome.
The solution? A Mini Spool System for 3D Printing Pens, with which you can use your 3D printing pen to weld together the parts after printing them. The unit holds 1.75mm filament coiled under its own tension in a tidy package that doesn’t interfere with feeding. Since different 3D pens are shaped differently, the interface to the pen is a separate piece that can be modified or changed as needed without affecting the rest of the design.
We’ve seen some interesting innovations with filament holders before, like this entirely 3D printed filament holder, but a mini spool for a 3D pen is definitely a new one.
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.
