Z Belt Driven Zyltech Gear V3 Remix

thingiverse

I had to remix some of the parts of this design to be able to work with a **Zyltech Gear V3** printer. I started out redrawing all the parts in fusion 360 for a Single Z (ultra low) version. The only parts I really needed to change were the bottom idler mounts & the Z-Plates. Since I had taken the time to redraw them, I also changed the parts more to my liking. My hole tolerances are a little looser than original design. My bearing holes are 22.4mm, M5 holes are 5.5mm & M3 holes are 3.5. Think I made all the plastic where the T-Nuts connect 6.2mm-6.5mm thick. I had to adjust the **Rt_Z-Plate** & **LtMotor_Z-Plate** to match the belt path that worked for my machine. I also made all the parts so there is no overhangs. I have 0.25mm clearance between the Belt clamp on the Z-Plates. I used a M3 locknut for the belt tensioning screw instead of regular nut. I changed the Transmission part to use just one part & beefed it up some. I am using a purchased 80T Gear Drive Pulley instead of the printed version. I have the controller board on the outside of my machine attached to a side 2020 frame, so if you are using this on a stock Zyltech printer, you probably want to use LTTopIdlerMount.stl instead of the LTTopIdlerMount_2020ShortSide that is fusion 360 assembly file. I have not installed this yet, but did print all the files. I have another project to test the M8 smooth rod on & didn't want to buy another one unless that design works. I included all the STL files I used as well as a fusion 360 assembly file which should make it easy for you to change anything that does not meet your requirements. I printed: 2 - **LeftBottom_Mod.stl** (same for both sides) 2 - **BottomBeltMotorBracket.stl** 1 - **LtMotor_Z-Plate_Mod.stl** 1 - **Rt_Z-Plate_Mod.stl** 2 - **BeltClamp.stl** 2 - **BeltCover.stl** 1 - **Rt_Top_Mod.stl** 1 - **LtTopIdlerMount_2020ShortSide.stl** Use **LtTopIdlerMount.stl** if you don't have the side controller board mount like I do 1 - **Transmission_Flat.stl** I used recommended 5 Perimeters, 5 top, 5 bottom & 55% infill. I also printed the **LtTopIdlerMount.stl** with a brim. Fusion 360 assembly file should show all the hardware you need. All M5 T-nut holes are sized for M5x12mm screws. Let me know if I missed anything.
