Mine Trolley Prop for Stop Motion

3D model description

Think Indiana Jones and the Temple of Doom, Hoodwinked, and maybe some spy vs spy and you have an idea of what I have in mind for this model. When I look at some of the pictures of mine trolleys on the web, this looks nothing like them, but that's OK.

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 so can ride on rails up to about 40mm between rail centrelines. The 3D printed bit is the chassis. It is intended that the deck and anything else mounted on the chassis is up to you.

The box on top was made from iceblock sticks stuck together with PVA glue. There is 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 have not included an STL for this part seeing as it is so simple to construct anyway.

Things you will need in addition to the printed bits;

3 x 4mm rods of some sort for the axles. These are cut to 55mm long. I used dowel.
Popsicle sticks. The dimensions for the “planks” are provided here as a suggestion and are based on the standard popsicle stick size available here which are 10mm wide x 2mm thick x 113mm long.
13 x 100mm long planks
10 x 40mm planks
8 x 50mm planks
2 x 58mm planks
4 x 15mm planks
Small screw to hold on the control lever if you are using it.
1.5mm rod for the control lever
Some electrical tape or duct tape to made the handle on the control lever.
Glue. I use an epoxy glue, buy 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 will 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 will 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 have also included an obj of the assembled model, and a .blend file in the downloads.

Also the models and additional information are available on my website – http://www.techmonkeybusiness.com
