Basically its a Voron v0.1 but with three belted Z instead of a single motor with integrated leadscrew. More information about the project can be found here:

- 3x Nema17 39mm stepper motors
- 3x ~500mm GT2 Belt
- 3x GT2 16T Pulleys
- 2x MGN7H Linear rail
- 1x MGN9C Linear rail
- 6x F623 Bearings
- 3x Spacers for bed
- 1x MCU with minimum 5 drivers
- 1x EBB36 CAN board
- 1x U2C CAN interface
- 7x Nutbar for 1515 extrusions
With regards to space and holding force 39mm Nema17 steppers was choosen. Ended up going with stepperonline motors from amazon.

In total 6 drivers will be needed, A, B, Z1, Z2, Z3 and E. Since I will be using a CAN toolhead board the MCU will only need 5 drivers. After some searching I landed on a used SKR 1.4 Turbo. It included 4xTMC2209 drivers and I have one extra from previous CAN conversion.
Will be using a ebb36 with an u2c from btt salvaged from my Trident.

The Tri-Zero needs two extra MGN7H 150mm rails for the two extra Z. As recommended by the designer of the Tri-Zero the X rails will be upgraded to a MGN9C rail and the old one repurposed for Z. One additional MGN7H was bought.

for this build I will be using ASA filament from 3DO. Base color will be anthracite and the accent ratrig green.
