Improved silicone sock for RED LIZARD K1 PRO CHC

The default sock for this hotend wasn't really doing its job, so I made a thicker one that covers a little better.

You'll need red silicone RTV/gasket sealer for this. I suggest printing out of PETG at 0.3mm layer height, washing with soapy water and casting with the RTV.

Update 27/01/2026: Made the walls thicker (4.5mm) and taller to avoid thermal issues. You can find it in the v2 folder.
