This is a Z-axis leadscrew decoupler designed for a TR8 leadscrew. It decouples the XY plane from the leadscrew. The design is similar to an Oldham decoupler, but uses a dovetail to keep the parts together.
It's compatible with the Rat Rig V-Core 3.1 design, since the original model was from Rat Rig. I modified the design for 3D printing.
The sliding dovetail has a clearance of 0.2 mm (STEP file provided if this needs to be adjusted). Mounting holes are M3x5 (2.8 mm diameter).
