Flsun QQ/QQS Biqu H2 mount

thingiverse

Failed to find a mount for Biqu H2 on the entirety of the net, se here's a quick duct tapey solution: it mounts the H2 underneath the effector plate, and as such trades ease of access for some print volume I used M3 screws to mount the H2, and M4 in the outer holes to press it against the effector plate; A second identical part can be mounted to the bottom of the H2 to provide a place for the Z probe mount to be fixed- use 10mm M3 bolts, or the included 12mm ones with washers- and 2 M3 nuts !!! IMORTANT: you will need to shave off a bit from the cooling fan housing for it to fit the stock arms; the motor has to be rotated 90deg to one side; The firmware NEEDS to be updated- set the Z_MAX_LENGTH to 280 (or such, depending on nozzle length); and set the new e-steps and retraction, of course Use something tough, heat&creep resistant- PETG worked for a while (unsure as to how much longer, though)- current version out of Fiberlogy PA12-CF15; seems something like CPE HT would work well- polyesters seem to 'grip' screws nicely in my experience Print with thick walls (>1.5mm), top&bottom (>1mm) and for high layer adhesion- low fan, high temperature
