Geeetech Mizar Direct Drive Bracket

thingiverse

A remixed bracket designed to use titan extruder, pancake stepper and MK8 hotend (ie original creality clone for the Mizar). This might work with the Mizar M, S or Pro...no idea as I don't have them but from what I can see that all use the same hotend assembly. I remixed this to print flat to ensure easy printing with minimal support as well as more accurate installation. The shim is also included just in case your titan extruder needs to be moved forward a bit. 0.6mm was perfect for me but scale it up or down on the Z axis to fit your setup perfectly. This bracket will align the titan extruder output directly above the hotend for a straight in feed. In my case this required a 112mm ptfe tube. You'll need to recalibrate your e-steps if you add a titan extruder. Start off in the 400 range and you should be very close.When installing you'll want to press the upper POM wheel spacers into the bracket holes. It's a tight fit but they will go in with a bit of pressure. I used channel lock pliers and then pressed the face of the bracket against a firm surface to set them all the way. Reinstall the whole assembly on the X axis and adjust the POM wheels and belt tension as needed.Coupled with this I added a volcano nozzle and this has turned this thing into a PET beast. Prints off PET bottle filament like a champ now. If you go this route you might want to consider 2.5mm ID ptfe tubing just to give a little extra clearance. This stuff is stiff enough so little chance of it binding.Printed with PETG at 260°C at 80MMS on a Kywoo Tycoon slim. 0.4mm nozzle gave very accurate results with little post processing.
