• Mix & Match: Print different parts in different filaments to create your own unique color combination!

🖨️ Print Settings & Recommendations

To ensure the internal gears and rotating face core spin smoothly, please follow these printing guidelines:

• Layer Height: While Roby prints fine at 0.2mm, using 0.16mm or lower is highly recommended for smoother curves, tighter tolerances, and an overall premium look.
• Infill: 15%–20% (Gyroid or Grid recommended).
• Supports: The main body and head shell may require minimal build-plate-only supports depending on your printer’s bridging capabilities. The internal rolling eyes core is printed split/flat to avoid supports on functional geometry.

🛠️ Assembly Guide

Assembly is quick and mechanical, though a few drops of superglue are required to secure the outer shell at the very end.

Step 1: The Face Check (Crucial!)

⚠️ Important: Before gluing anything, insert the yellow/colored eye pieces into the black eye sockets of the internal rolling core. Check that they fit perfectly and sit completely flush with the surface. If there are any elephant feet or tiny print imperfections, give them a quick sand. They must be flush so the core can rotate inside the shell without jamming! Once verified, glue the eyes permanently into the core.

Step 2: Assemble the Internal Core

1. Connect the rotating core halves together around the internal alignment peg/block.
2. Insert the eye pieces into the eye sockets

Step 3: Set the Shell & Arms

1. Place the lower body shell on your workspace.
2. Drop the assembled internal eye core into the lower body sockets.
3. Slide the left and right arms onto the side connector pins. Test the rotation now to ensure the face flips smoothly when you twist the arms!

Step 4: Final Closure

1. Place the top head shell (Antenna or Loop version) over the core, aligning it with the bottom shell.
2. Once you are 100% happy with the mechanical movement, apply a few small drops of plastic-safe superglue (CA glue) along the seams/alignment pegs joining the top and bottom outer shells.
3. Hold firmly for a few seconds until set. Be careful not to get glue near the rotating internal core or the arm joints!
