A mod of the Voron Trident that replaces the 3 leadscrews with belts and modified Z-Drives from a 2.4. This is in the very early stages of development and though a fully-functional printer has been built, some of the parts are not yet fully tested. The existing printer is producing excellent prints, though many changes will be coming in the following months.
This first version places the Low Voltage Electronics up top, though I do hope to create a version in the future which is more closely matched to a stock Trident Build. The second version will have the Z drives and low voltage electronics located on the bottom, same as in a standard Voron Trident or 2.4.
A huge thank you to @clee for lots of help in planning, designing and generally supporting the development of this 3Dprinter.
Since this is the most common question when posting about this printer, I will get this out of the way.
- Much higher Z speeds and accelerations when compared to lead screws. Tested so far at 200mm/s and 1000mm/s^2 without issues.
- Avoids the usual drawbacks of leadscrews regarding wobble and backlash.
- Similar cost to a Trident with lead screws, given the relatively high cost of steppers with integrated lead screws.
- Why not?
The cost of this modification is approximately $145 USD. If the 3 steppers with lead screws are not purchased, the cost over a stock Trident build is approximately $40 USD.
Due to max size for files on GitHub, the CAD file can be downloaded from Dropbox. There is a greatly trimmed-down file available in the CAD folder, but this link contains the most up to date full model.

Upper deck panel can be created from the bottom panel. DXF is included.
Deck Panel remains the same.
Rear Panel may benefit from some cutouts below the gantry extrusion to allow easier routing of wires from below deck to above.
Top LV electronics panel is a square with the same outside dimensions as the bottom panel.
