Looks like it’s this thing: https://www.thingiverse.com/thing:1068443
It’s a maddening, yet somehow fun hobby. If you do it just remember it’s better to get a high quality small one vs a shit huge one.
I started with a CR10 knockoff that was a fucking nightmare. Good for learning how they work, but an overall shit user experience. I upgraded to an Artillery Sidewinder X1 and all my headaches went away (for the most part)
If you like tinkering it will be fun.
The actual CR10 is a fucking nightmare lol, PRUSA is a better way to go but I’ve heard The Sidewinder X1 is pretty decent.
