Biqu B1 Stock and Titan Direct Drive Mounts

thingiverse

I designed 2 mounts for Biqu B1. They both are designed to mount to the stock printhead of the b1 without altering it. This will remain in a WIP (work in progress) status until I take the time to create a nice writing on how to install these. Unless someone else wants to. I assure you I have printed and used both of these mounts without any fuss. OEM: Is a mount to use the Stock extruder (or any metal extruder) and the stock Stepper motor. It is a heavy piece and you can print successfully at 60mms 30-40mms on the walls. This can give you Direct Drive performance without spending a dime unless you don't have M3 hardware long enough to mount this. If you use the stock extruder I highly suggest doing the mod pictured in the last couple photos. You drill out the exit to 4mm so the PTFE tube can slide all the way through. You can then slowly cut and shave the end to match the extruding gear and idler. Just remember to account for this extra length when measuring and cutting a PTFE tube. For the stock extruder with this mod I used a PTFE 61.00mm long. DO NOT CUT THE FINAL LENGTH UNTIL YOU SHAPE THE END MATING THE GEARS. TITAN: I really thought the OEM was a bit heavy and probably would wear on the "V" slot rollers prematurely. I wanted less mass in motion. So for $28 I picked up a 1amp Short Body Stepper Motor and a Titan Clone from Redrex. I will add links in at the bottom. These are what I found to be the best "Bang for Buck" solution to reducing weight and keeping torque up. I also reduced the over size of the mount because the structural integrity could be drastically scaled down. The overall weight of this set up is lighter than just the stock stepper motor by itself.
