All parts in STL format for easy printing (assuming you have a second printer). Will continue adding printable files here as needed, updating this description each time. A) Base plate for One-Up/Two-Up printers that was missing from original Kickstarter kits (basicHEM_r3.stl). B) Alternative for QU-BD's design of the Y-drive mechanism that adds some sturdiness, allows the belt guide to operate more smoothly. Replaces the entire Y-Drive mechanism (except for the bearings and bolts). C) Spacer Plates for Two-Up printers to correct Z Screw misalignment. Just install under the linear bearings of the X Gantry system.
