This challenging print is a take on the classic pin screen toy.

Place an item below the pins and they'll move to mimic the contours of the object!

Printing

Test printing only a few pins at a time to make sure your they'll stick well to your print bed. If they do, slowly increase the quantity per print.

This project includes a 10 pin option that holds the thin end of each pin down to limit curling.

Required Parts

• 200 pins
• 2 Grids
• 4 Spacers (use 6mm for a compact design or 12mm for more stability)
• 8 M3 nuts.
• 4 M3 bolts that are long enough to pass through the nuts, grids, and the spacers you chose.
   

Assembly

• Align both grid pieces so their holes match up. There's a tiny circular indent on one side to help orient these pieces.
• Insert an m3 nut into each of the 4 spacers.
• Place 4 spacers between both grid pieces and secure with the 4 m3 bolts. It does not matter if the bolt head faces up or down, so choose the direction that looks good to you.
• If no optional parts are being added, secure the bolt with the remaining 4 m3 nuts.

How I Designed This

This was a lesson in getting around the limits of 3D printing! Printing tall and thin items (like a pin) vertically is normally torture on a printer.

This required a new pin design - one which could be printed sideways, and still have no overhangs. By placing the long neck of the pin on one side, and changing the head to a hexagon, each pin is now much easier to print!
