My original sock got caught on a print and tore off. Wasn't really useable anymore so I had to toss it. Klipper started throwing errors anytime I tried to print at higher temps with a cooling fan on so I needed a new sock.

It's a pretty niche hotend so the only ones available to purchase are from AliExpress and I didn't want to wait 1-2 months for delivery so I designed a mold to make my own.

You'll need:
- These printed parts
- 2x M3 nuts
- 2x M3x30 or longer bolts
- 1x M3x40 or longer bolts
- High temp silicone (I used Permatex "Red RTV" Gasket Maker from Home Depot, it was like $6 for a tube)

Instructions:
- Print parts, no supports, use as high quality as you can (I used 0.1 layer height). PLA is fine.
- Squeeze a bunch of silicone into part A. Use more than you'd think -- it's easier to trim off excess than it is to restart the whole process.
- Insert part C into part A, flat-side down. The tolerances are essentially zero, so try your best to press it in.
- Squeeze a bunch of silicone into part B.
- Put the parts together and use the longer M3 bolt to align part C.
- Use the shorter M3 bolts and nuts to clamp the assembly together. Excess material will ooze out the seam and the two bleed holes in part A.
- If it doesn't seem like enough oozed out, you probably need to open it back up and squeeze more silicone in.
- Let sit for a few hours, the longer the better.
- Open it up and try your best to extract it without tearing it all up.

After a little bit of cleanup you should have a well-fitted sock.
