BIQU H2 Adapter Parts for V1Engineering MP3DP V2

thingiverse

PLEASE NOTE: this is an untested design as the printer is not yet built. I've test fitted the parts and they work on the extruder and the default X carriage that is part of the MP3DPv2 (as shown). REV1: Fixed the BLTouch Fan bracket and Upper Bracket for issues Full details regarding development of this assembly can be found here: https://forum.v1engineering.com/t/mp3dp-v2-biqu-h2-direct-drive-hotend-combo-option/31340 MP3DP v2 Can be found here: https://www.thingiverse.com/thing:2754519 Here are the parts I made to adapt the BIQU H2 Extruder to the V1 Engineering MP3DP V2 (not sure if it'll work on a V1 but will not work on the new V3 Repeat). Most of the screws are either supplied with the H2, only a couple outliers. BOM: BRACKETS: 4ea @ M3x6 to mount to the top and bottom of the H2, then 2ea @ M3x8 and 2ea @ M3 nuts to mount the H2 assembly to the standard MP3DP v2 X carriage. Washers on the nut side and Loctite on the M3x8s recommended if not using locknuts. PART COOLING FAN: Use the supplied M3x8s to mount the fan shroud, and 3ea M3x12 to mount the fan to the bracket. 3ea M3 Nuts are recommended, even if the screws engage into the bracket. this is a vibration area, so the nuts are added insurance. This fan shroud is not mine, that can be found here: https://www.thingiverse.com/thing:4757657. I plan on modifying this later for H2 V2 heat blocks. BLTOUCH FAN GRILLE: Use the screws provided by the H2 kit to mount the grille to the H2 assembly and use the BLTouch supplied hardware to mount to the grille bracket. The BLTouch Sensor offsets: X= -42.00 This will vary with the antivibration pad use/thickness. I printed this with NnjaFlex, but you can print it with ABS or other high temp material of your choice. I highly recommend using it as not only does it dampen the fan and BLTouch, but it also provides an airgap between said mount and fan blades to dampen vortex hissing. Y=0 (yes, i made this easy for you... you're welcome... ok, you got me, it was for my benefit...) Z=-0.50 to -2.00 (but double check this. the tip is at the very bottom of the heat block when retracted)
