Tips

• Have a 1st layer squeeze so the plates are flat instead of having print lines.
  • (Balls will get stuck in print lines)
• You need all 4 screws on all 4 corners, for both top and bottom assembly.
• Do not over tighten the screws. It will warp the plates
• Tape the coin hole so you don't spill them around.

Assembly

Clean out the support from the magnet hole on the bottom of the chip plate and insert a magnet no bigger than D8mm x 3mm.

Use [4x] M2x6mm screws to attach the top rim to the stencil support.

Use [4x] M2x8mm screws to attach the chip plate to the base AFTER inserting the magnet into the chip plate piece.

The base has an opening for a few coins to weigh the whole jig down for better stability.
