GEEETECH A20M hotend mount for Homyl Color Switch Extruder
thingiverse
Replacement mount for stock hotend mount on a Geeetech A20m printer. The stock hotend is designed to mix or switch 2 colors. However, they are prne to clogging. As several other users have already posted things to use other brands of switching hotends I designed this one for the Homyl 3D Printers Assembled Color Switch Extruder which I found on amazon.ca. The mount attache using only the top 2 bolts The original use 4 with the bottom ones being installed from the rear side which were a PITA to get at and 2 works fine. I designed a micro adjuster for the BLTouch sensor. You'll need some M3 bolts and screws plus one machine screw to secure the parts cooling nozzle. Cooling is done by 2 50x15 blower fans. I moved the little connector block higher and pointing towards the front for ease of connecting the various connectors. https://www.amazon.ca/gp/product/B07HYWXT61/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
