BLV Mod MGN-12H DotBit Direct Drive Nema and 5015 Fan Mount

thingiverse

Designed a nema 17 mount for the BLV mod which uses MGN012H linear rails with an LJC18A3-B-ZBX_NPN capacitive bed sensor. I used a bowden setup for the longest time but found the pendulum effect of the bowden tube moving to the edges of the bed caused under-extrusion. You will need to purchase some additional hardware for this mod to work: 4x 2" springs for the heatbed 4x 6/32"x2" tapered head screws to attach the heatbed to the frame 4x 6/23" Nylok nuts 2x M3x45x.5 screws to mount the Dotbit & fan mount to the Nema 1x Pancake Nema 17 stepper motor 2x M3 screws long enough for the GT2 belts to rap around 2x M3 nuts 2x M3 threaded Inserts - Melted in to the bottom of the Nema mount to help secure the GT2 belt screws. 1x 3030 fan E3D mount 1x DotBit Dual Extruder 4x zipties The fan mount also has mounting holes for an ADXL345 and spacers to keep the screws from touching any electronic parts on the ADXL345 board.
