Description

UPDATE: 17.09.2025:
I've added a new version, which uses a ¼ inch bit instead of the pencil.

Since a lot of people have asked about the spool holder visible in the background: This is not my model it is one I have found on Printables. However you can use any spool holder you might already have laying around or even improvise something using a broomstick and a few clamps for example.

UPDATE 29.03.2025:

I've added a small chamfer at the beginning of the threads, since they were a little hard to start.

This is an updated version of my filament respooler. This model allows you to screw an empty spool of filament into a drill in order to transfer the filament from another spool. It unlike many other models, it doesn't require any additional hardware except for a regular pencil. I received a lot of feedback on my old model, leading to two major improvements:

The tolerances in the threads are looser, making it a lot easier to use.
I added a gripping surface to the edge of the parts, making it more comfortable to screw them together. The old version had quite sharp edges.

There are two versions of the part. The first version has a knurling pattern on the gripping surface, giving it a luxurious feel. This however is very slow to print because of it's fine features. So if you're in a pinch and need the part fast, I recommend the version without the knurling.

To use this device simply clamp an empty spool between the who parts and stick a pencil through the hexagonal hole. The pencil which I used is about 7mm thick (between flats). This seems to be quite a common size, at least here in Europe. Than just mount the pencil in an electric drill and put the old spool onto a filament holder. Then just spin up the drill and start spooling. While respooling make sure to guide the filament with a small piece of PTFE tube. The windings don't look perfect but it certainly works if you just occasionally need to respool a roll of filament.

This is what the finished spools look like:
