Square Mirror Puck twisty puzzle

Recommended Print Settings:

• Nozzle: 0.4 mm
• Layer height: 0.16 mm (Variable layer height for Core1 and Core2, with 0.16 mm maximum)
• Material: PLA and/or PETG
• Wall loops: 3
• Top Shell: 6 layers
• Bottom Shell: 4 layers
• Infill: 25% gyroid

It can be printed with a standard 0.2 mm layer height, but you may need more clearance, additional lubricant, and a longer break-in period.

What You Need:

• 1 pc. M3x8 or M3x10 mm button head hex socket screw + washer
• 2 mm hex key
• Thick, plastic-compatible lubricant, such as 50,000 cst silicone oil or SuperLube grease
• A 3 mm drill (optional, for cleaning the hole in Core1)

Optional:

• 4 pcs. D5x2 mm neodymium magnets (or D5x max. 2 mm)
• CA glue (and activator, which can be handy)

Clearance:

For various reasons, you may need different clearances. For example: A fully PLA print worked well with the default clearance in my case. But a PETG core required a clearance of -0.10 mm paired with PLA segments.

Minus clearance: tighter fit

Positive clearance: looser fit

Important Notes:

Clearance Check:
It's hard to determine if the clearance is correct until the puzzle is fully assembled and lubricated. You may want to glue the magnets after a test fit. Don't forget to degrease the surfaces before gluing. Also, note the magnets' orientation as shown in the photo.

Break-In Period:
The puzzle will break in over time and become smoother. You can speed up the process by rotating the segments back and forth multiple times.
