The servo horn on my Auto3DClippy has broken twice now, and I am having trouble finding a link to replacement horns. Does anyone know where to get replacements? In the meantime, I'm going to try to modify the Auto3DClippy to use the metal horn.
Any help would be appreciated.
I was left without things to do this weekned. I went and remixed bills updated Digital 3d Clippy design from the top of this thread. This one should fit the sprite extruder though I have not tested it out for fit or function. (the sprite is a pain to work with since the tension arm and gear all right next to the filament inlet. https://www.tinkercad.com/things/2BoJY2VfoV6-digital-3d-clippy-for-sprite-extruder
Anyone happen to create a box for the buck converter suggested by Bill, before I go off and make one?
Ok, I've modified a new Digital 3DClippy to use the longer metal horns. I'm printing it right now... I'm also testing it with higher voltages and have a very simple solution for setting it up. Basically, you'll need a 12v Y adapter and a variable buck converter. Then you'll be able to disconnect the red/black wires from the servo and feed power directly into them via the buck converter's output. Use the Y adapter to feed 12v power into the buck converter. Here are the ones I am using for testing: Servo Horns: https://www.amazon.com/gp/product/B09JLLWDW2 Buck Converter: https://www.amazon.com/gp/product/B081N6WWJS
2.1mm Y adapter: https://www.amazon.com/dp/B082Y1PQ6C
Optional Power Plug: https://www.amazon.com/dp/B07JMY5XXT
And here are the Tinkercad files I'm using for the Digital 3DClippy. (It says Sovol, but it's really the generic one... I'll update that once I validate it all.): https://www.tinkercad.com/things/eDLXiIOsWrO-digital-3dclippy-for-sovol-sv-08
Note, these are no solder solutions... I'll also have a cheaper method if you feel like soldering it, but I need to test all this first.
You'll want to use the Red set for the metal servo horns, and the Yellow for the plastic 4 way cut down horns.
I'll post back here once I've validated it all tomorrow.

Another update:
The printed servo horns cut a few pieces of filament before slipping. I'll probably get one of the aluminum servo horns off of Amazon.
I found these horns on Amazon: https://a.co/d/dp5FxeV
Would these be compatible if my printed ones fail?
UPDATE: I was able to print out the servo horns from the Tinkercad file with 20+ perimeters on a 0.2mm nozzle, and they seem to grip well manually moving it back and forth (I can hear the metal gears inside moving with the horn). I have yet to test it with the servo moving itself.
You should be able to find them on Amazon. But I shop here for lots of things like that...

If there is a local RC toy store near you, they should have them as well.

Did you print them or cut it down from the 5 sided horn included with the servo? It should be the 4 sided one... I've never broken one in over a year of testing it. Also, make sure you're not fighting a bad print or something that is causing it to hit something. Only the filament should be the force applied to it.
