Today I Printed: A TPU Feed

Mon 18 January 2021

I’m breaking my rule of not posting printer upgrades, but I’m really proud of how well this turned out.

A filament feed for my tarantula pro extruder, with tighter tolerances and extra bits to keep flexible filament from going in the wrong direction and getting stuck. A pain to design and iterate on because it meant unloading the filament and taking the extruder off between each print.

That's it

It fits nice and snug in the extruder.

That's it

Now I can finally print with my new TPU filament!

Here it is on Thingiverse, and here’s the OpenSCAD file.
