About this 3D model
Separated the model into 3 main pieces to minimize any warping issues and negate the need for any support. Added dowels for the internal parts. Single plate printing. Fits together perfectly. Just glue the 3 main parts together and place the internal parts. Dowels slide in nicely, but still allow easy removal. HOW TO PUT IT TOGETHER: A YouTube streamer posted a great video of his print of this and detailed assembly instructions. Assembly starts at about 6:15 or so. https://www.youtube.com/watch?v=dt6IdCPctu0. Remixed in Tinkercad.com https://tinkercad.com/things/58ME1FhYSL7-rubberband-gun-all-pieces-single-plate
