Update 2014.11.19: Added files (V2) with adjusted dimensions for improved performance

This design consists of 3 parts: a bracket that mounts to the x-axis, replacing the wooden hardware, a nut trap that is free to slide along x-axis bracket, and a piece to hold the z-rods vertically.

Parts are optimized for printing at 0.3mm layer height. Suggested 25% infill and printing in heat resistant materials such as ABS, nylon, or PET


1. hold motor shaft with a pair of pliers and remove rod from plastic tubing connecting motors to z-rods.

2. lift x-axis and remove z-rods.

3. unscrew t-slot bolts on wood piece with nut trap for z-rods and replace with printed z-iso_bracket

4. slide z-iso_nut_trap onto nut on z-rod and thread z-rod through slot on z-iso_bracket.

5. Repeat step 4 for 2nd z-rod

6. Reattach z-rods to z-motors using plastic tubing

7. Remove bolt at top of z-axis linear rail (this attaches z-rail to top of wood frame)

8. Install z-iso_rodfix by threading z-rod through hole and attach to wood frame using bolt removed in step 7.

9. Repeat step 8 for 2nd z-rod.
