Haldis 3D Red Lizard K1 hotend silicone sock mold

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.
