Pin Screen Toy - Pixel Edition

prusaprinters

A 3D printed take on the classic pin screen toy.Place an item below the pins and they'll move to mimic the contours of the object!https://youtu.be/ewmXIO9IlzEhttps://youtu.be/OHlQux6WmxQ PrintingPrint spacers and caps so that the hexagonal nut shaped hole is facing up to avoid overhangs.Test printing only 4 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.If pins are curling of the bed, add a sacrificial 1 layer high rectangle to the end of the pin, as shown in the video above. Required Parts576 pins1 Grid Top1 Grid Bottom4 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. Optional parts4 Spacers to act as feet. Chose a length that looks good.4 Caps to hide the head of each bolt.Thin sheet of plexiglass with holes for 4 bolts to act as a lid. If adding a plexiglass lid, you'll also need 4 more spacers to hold the lid above the pins.Plexiglass Frame (Not necessary for plexiglass, but provides a visual edge and support) AssemblyAlign both grid pieces so their holes match up. There is a tiny circular intend 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 ThisThis 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! Can I sell copies of this?Yes!
