Compact Direct drive For Ender-3
thingiverse
Direct Drive Set For Ender-3 Used Dual gear Red extrder and TriangleLab all-metal Hotend, but it is also compatible with stock hotend and stock extruder. I used Usongshin 17HS-4023 motor(Nema17 23mm), but stock 40mm motor is also compatible (but not recommended for gantry total weight.) this thing needs lots of support, so I don't recommend PETG for this thing. (PETG is very bad on support removal) Designed for 4020 fan, but you can use stock 4010 fan. M3 nut x5 M3 8mm x5 M3 13mm or 15mm x1 M3 25mm or M3 8mm(hard to install) x4 M3 20mm(or 16mm) x2 1mm spring washer(for hotend) x2 Probe offset : X : -34mm Y : 6.5mm used -0.823mm for Z axis, but it differs by nozzle kinds and assembly (I use Trianglelab Hardened Steel nozzle)
