About this 3D model

Remixed Belt-Driven Z-Axis Mod for BIQU B1 This is my adaptation of the Belt-Driven Z Mod originally designed for the Ender 3 by Kevin Akasam ( link to original mod ). I modified the design to fit the BigTreeTech BIQU B1 printer using a belt-driven Z-axis kit from Aliexpress ( kit link ). Changes and Adaptations: Right Bracket (V3.7) Adjusted the bolt location inside the bracket, moving it 0.5 mm further from the extrusion for proper alignment. Bottom Part Redesigned to ensure it could be securely mounted on the BIQU B1's extrusions. Z-Endstop Switch Fixed using the left screw of the clamp mounted on the left plate, positioned close to the extruder. Z-Endstop Adjustment Screw Utilized the right screw from the bottom part and added approximately four washers for proper alignment with the switch. Notes: The kit I used was a great fit overall and required minimal modifications beyond the changes listed above. If you're looking to upgrade your BIQU B1 with a belt-driven Z-axis, this remix provides a practical solution.
