The standard MakerSlide carriage plate doesn't provide direct support for a 181x181mm Ponoko P1 2D laser cut panel (shown in yellow) used as a horizontal sliding stage. A3WB solves that problem by integrating a MakerSlide carriage with beams that form a stable base for arbitrary P1 panels. The P1 panels attach to A3WB with four M3 screws at extreme ends of the panel to maximize the unobstructed panel area. The M3 panel screws are mounted on two primary beams that stiffen the stage and make it rigid. A pair of MakerSlide V-wheel bearings, attached to each primary beam with two adjustable F5E8 eccentric spacers, allow the stage to slide freely along the MakerSlide. An additional pair of secondary beams span and connect the two primary beams to provide longitudinal panel support.

• 2D laser-cut parts sufficient to make two complete A3WB carriages

Each carriage requires:

• F525 M5 25mm button head screw (4)
• F50W M5 washer (4)
• F50L M5 lock nut (4)
• [F312 M3 12mm buttoh head screw] (F312) (8)
• [F30E M3 nut] (F30E) (12)
• [DGC3 GT2 belt clamp] (DGC3) (2)
• Acrylic glue

• version 1: UNTESTED Ponoko TBD

1. Practice fitting the pieces together to form a carriage and place it upside down (the bottom will have the most glue)
2. Disassemble pieces
3. Insert the two secondary spanning beams into the keyhole slots of the primary beams so that the secondary beams are resting in the circular holes of the keyhole slots. Partial assembly of the keyhole joints minimizes glue smear.
4. Apply glue to the keyhole joints and complete assembly of the keyhole joints.
5. Apply glue to the four overlapping joints of the primary beams and assemble
6. Apply glue to the primary beams along the bottom faces and attach the bottom piece
7. Leave undisturbed for 24 hours
8. Attach the MakerSlide V-wheel bearings as shown
9. Attach the GT2 clamps as shown
10. Attach the desired P1 panel to complete the sliding stage
