Modded the step file from an already excellent extruder to suit my needs.
To build the exact extruder as pictured, you need to print all 4 parts (remember to mirror the end_plate and midsection) along with the mirrored version of the original M4 STLs (except the main body and the end plate since you'll be using this modified design).
Modifications from the original: Changed the end_plate mounting holes and hole position to accept M3 screws Added an angled mounting bracket to allow the hatch to open while maintaining a small footprint Altered the coupler design to a 3D printable one, which also has zero play because it uses ridges to clamp onto the PTFE tube. Removed the stud on the end_plate to suit my coupler design.
Hardware needed: 2 M3 nylock nuts and 2 M312mm bolts to mount extruder to the mounting plate 2 M3 nuts, 1 M310mm bolt, and 1 M3*8mm bolt for the coupler.
Print Instructions: Use bridging, no supports needed, orientation is exactly as STL orientation. Use the Voron M4 print settings and material for end_plate, midsection, and ultra coupler; bracket works fine with any material but needs good bed adhesion (I used PETG).
