M1113 PMV (APC)

thingiverse

When I was a young man in the military, I drove an M113 PMW (APC) and now I've decided to create one from scratch using my 3D printers. I've successfully designed one and I think it's good enough. It's made from information, pictures, and my memories, so I can't guarantee 100% accuracy. I drew it in Fusion 360 at a 1:1 scale and reduced it to 6% (Length:292,Breadth:162,Height:150mm) so the big parts could fit on my FolgerTech FT-5 printer. For Idler, Track, and Road wheels, there are STL files for single and dual wheels. You can print single wheels and glue them together or print double wheels. I've kept the wheels stationary. The 2 Track Shoes consist of 130 shoes and 260 holders. I added them with 1mm steel rods (2 pieces per shoe) so they can move. Glue two rods into one holder, let it set, insert two shoes, apply a small amount of glue to the end of the steel rods, and lock with the other holder (65 times for each side). Glue RoadWheels supportArm to the body and attach Track and Road wheels in place. Attach Idler wheels to the Idler Arm; wait until it's glued to the body to tighten it. There are STL files if you want to print the rubber foot separately. All hinges for doors and ramps, etc., are printed with a hole in the middle so 1mm steel rods can be used as shafts. If you plan to print it smaller, consider thicknesses, which may become very small. A short video shows the order I assembled my M113 (Zip file). There's also a Parts List available. Filament: PLA Infill: 30% Support: Yes Approximate length of required steel rod: 5.3 meters, 1mm diameter.
