jlangholzj's Ender 3 v2 Phaetus Dragon Hotend mods

thingiverse

This is place for my alternative parts to jlangholzj's Dragon hotend mount for Ender 3 V2 - those parts are direct replacements for the original ones with possibility to mix'n'match them according to user's liking (unless otherwise stated). Kudos to jlangholzj for his design. Intro: I've found the original gantry mount by jlangholzj very promising; however, at my first try the bowden coupler socket cracked during assembly. I've fixed this one and took an additional effort of adding fillets to alleviate potential material tension and to lower shear force at perpendicular planes in case of failure (like nozzle bumping into bed). Tolerances around new bowden socket are somewhat tight for screw heads (0.25 mm clearance for standard caphead ISO screw) but this should pose no problem for a calibrated printer and otherwise can be easily fixed with sandpaper. As long as my own setup is (slowly) evolving I expect to commit here some other modifications. TODO: 1. gantry mount: * add hole on gantry mount corresponding to additional holes made by Creality on Ender 3 V2 gantry (some first few production series of V2 don't have them but maybe someone will find them useful) * add some cable management elements (hook at the top?) * make version for helicoil and/or insert nut for bowden coupler instead of printed thread 2. fan brace: * create fan brace for 2x4020 fans * add some cable management elements/holes Per part description: 1. Gantry Mount Reinforced This part has thicker walls of bowden coupler socket and filleted right angles (save for a few places where fillets could cause assembly problems). Can be printed both laying flat without supports and vertically with supports. The second option is recommended due to the printed thread.
