Print at layer height 0.2 with 3 walls, 5 top and 4 bottom layers and 15 - 20% grid infill.

I recommend printing the Middle section, Card pusher and Lever in PETG for its flexural strength . The top and bottom sections will be fine using any type of filament.

You will need

• 4 M3 x 12mm bolts
• 4 nuts M3
• 3M3 x 5 mm bolts
