3×2×1 slide cuboid

Warning: Thorough post-processing is essential! If you don't clean, sand and break-in the parts properly, the puzzle will be very stiff and hard to turn.

This is a fully 3D-printable twisty puzzle of 3x2x1 cube with sliding mechanism. The model is engineered to be assembled completely without screws. No MMU/AMS is required for printing. 

Performance Notes:

• Turning: The puzzle turns very smoothly once properly assembled and broken in.

• Tolerances: It does not corner-cut.

   

Assembly & Post-Processing Tips:

• Cleaning & Sanding: After removing supports, make sure to lightly sand any surfaces where supports were attached to achieve flush joints.
• Mechanism & Breaking-in: After sanding, take the parts that will slide against each other and manually run them back and forth several times. Do this for every piece until you feel the friction reduce and they move more easily.
• Assembly & Lubrication: Start assembling the model. Just before inserting the final pieces, apply lubricant to the cube's internal mechanism. Once the cube is fully assembled, perform several turns on every side to distribute the lube evenly and ensure a smooth turning experience.

Assembly instructions:

• Step 1: Break-in every pieces and core

• Step 2: Put inside the slide core the stake

• Step 3: Put on cores all pieces

• Step 4: Join together two assambled halves
