Mine Trolley Prop for Stop Motion

cults3d

Think of Indiana Jones and the Temple of Doom, Hoodwinked, and maybe some spy vs spy and you get an idea of what I have in mind for this model. When I look at some pictures of mine trolleys online, this looks nothing like them, but that's okay. The overall dimensions are 65mm wide x 70mm tall x 140mm long. The track gauge is about 38mm. The wheels have reasonably wide flanges and can ride on rails up to about 40mm between rail centrelines. The 3D printed bit is the chassis. It's intended that the deck and anything else mounted on the chassis are up to you. The box on top was made from iceblock sticks stuck together with PVA glue. There's nothing special about this. The iceblock sticks were painted with a sepia-coloured brown acrylic house paint without undercoat. This allowed the paint to penetrate the wood nicely and give an aged stained look. I haven't included an STL for this part since it's so simple to construct anyway. You'll need the following in addition to the printed bits: Three 4mm rods of some sort for the axles, cut to 55mm long. I used dowel. Popsicle sticks are also needed. The dimensions for the "planks" are provided as a suggestion and are based on standard popsicle stick sizes available here: 10mm wide x 2mm thick x 113mm long. You'll need 13 x 100mm long planks, 10 x 40mm planks, 8 x 50mm planks, 2 x 58mm planks, and 4 x 15mm planks. A small screw to hold on the control lever if you're using it is also necessary. Some electrical tape or duct tape to make the handle on the control lever will be needed too. Glue is required as well; I use an epoxy glue, but anything without too much flexibility will work. In the model shown here, the channel sections used in the buffers were cardboard. This meant that I ended up with a slightly dinged-up look to it, which suited the look I was after. The original digital model and all STLs include these channel sections. When you print this, you'll end up with a handful of small components. Some assembly is required! Unfortunately, I haven't been able to include a pdf of the instructions here, so you'll need to zip over to my website and pick it up from there: http://www.techmonkeybusiness.com/a-3d-printed-mine-trolley-prop-for-stop-motion.html I've also included an obj of the assembled model and a .blend file in the downloads.
