Remix of Eric Lien's Eustathios v2 Spyder Z-axis bed support, designed to work with a set of 1204 ball screws from Golmart. When attaching the ball nut, I'd recommend installing it so the grease port is accessible. The part was trimmed to increase z travel by 1.5cm.

The two parts are identical, except the left version adds an additional hole for a M5 z-axis adjustment screw.

Parts:

2 - 12mm ball screw

8 - M4x20mm countersunk screws

8 - M4 Locknuts
