Ghostbusters - extra Small proton pack

myminifactory

A compact toy version of the iconic Ghostbusters proton pack, scaled down to 50% for a fun and manageable build. This movie-accurate design makes it easy to print and assemble. **UPDATE**: To cater to younger kids, I've added a 60% proton gun attachment, perfect for little hands to grasp. The model is engineered to withstand rough play, with some parts molded directly onto the frame for added stability. To build this toy pack, you'll need: * Glue * 4 screws * Red, blue, green, and yellow filaments for the cables * Two strong magnets (30mm x 10mm x 4mm) to secure the gun to the pack * A flexible ribbon cable (I used an old IDE hard drive cable) * Black OD 13mm split-less loom tubing * Straps from an old backpack * Optional: foam for a comfortable back panel, secured with glue and the existing screw holes You can find printable stickers online to add more details at 50% scale. If you find the gun too small, try using the files labeled "60" instead. This model is free for all to enjoy!
