Pumpkinland - where pumpkins come to life

thingiverse

I wanted to create a Halloween decoration that fits perfectly on a desktop and runs on a sustainable power source. This project requires some tinkering, but I enjoyed designing and making it from scratch. I hope you all like it too. Models from Thingiverse: - Jack-o-Lantern from @thjelmfelt | Link: https://www.thingiverse.com/thing:2590046 - Pumpkin clips from @syure | Link: https://www.thingiverse.com/thing:3112280 - Realistic pumpkin stem from @Jyoungun76 | Link: https://www.thingiverse.com/thing:3182848 - 3D tree remixed from @NitroXpress | Link: https://www.thingiverse.com/thing:3916636 Modelled parts: * Pumpkin seats * Pumpkin base * Grave/switchboard Prints for the setup: * 3 X Jack-o-Lantern set (Full, 70%, 40% scale) (use the 'mid section with hole' part) * 1 X Base * 3 X Pumpkin seats (for Full, 70%, 40% scale pumpkins) * 1 X Grave * 1 X 3D tree (X,Y = 90% scale, Z = 100% scale) Other setup items: * 5 X M3-5mm screws (or can use the hot glue) * 1 X Fairy LEDs (similar to https://amzn.to/2BauGYe) * 1 X USB A 2.0 cable * 1 X moss/grass lookalike/dirt Assembly items/tools: Multimeter, wire cutters, soldering iron, hot glue Assembly: - Take the fairy light power box and carefully remove the circuit box without damaging the wires connected to LEDs. - Cut the USB wire while keeping the male USB intact. - Identify the power-carrying USB wires using a multimeter. (If you don't have one, it may take some trial-and-error.) Typically, dark and light colors represent negative and positive, while colors like green and blue indicate signals. - Solder/connect the USB to the circuit's positive and negative terminals. - Attach the USB circuit to the grave/switchboard print using screws. - Secure the grave to the top-left holes on the base plate. - Use hot glue to secure the outgoing USB wire to the notch in the back. - Place the pumpkin seats on the base plate, starting with the largest one on the top-left, followed by the medium-sized one on the right, and finally the smallest one on the bottom left or right. - Align the slots on the pumpkin seats to accommodate lights from top-left to right and then back to the bottom-left. - Assemble the 3D tree and attach it near the grave using glue. - Route the LEDs through the slots and landscape for a beautiful lighting effect. For lighting the pumpkins, you can bunch them and glue them on the seats or let them float inside the pumpkin for an interesting effect. For 20 LEDs, use 7-8 for the biggest pumpkin, 5-6 for the medium one, and 2-3 for the smallest one. - Apply moss/dirt/grass lookalike to the base plate. - Assemble the pumpkins and place them on the seats.
