When I was a young man in the military, I was a driver on an M113 PMW (APC) and now I decided to draw one and print it on my 3D printers.
I have made one and I think it is ok.
It is made from information, pictures and my memory so I can not guarantee 100% accuracy.
I have drawn it in Fusion 360 1:1 and scaled it to 6% (L:292,B162,H150mm)so the big parts can be printed on my FolgerTech FT-5.
For Idler, Track and Road wheels there are STL files for single and dual wheels.
print single wheels and glue them together or print double wheels.
I have not allowed the wheels to move.
The 2 Track Shoes consist of 130 shoes and 260 holders,
I have added them with 1mm steel rod, (2 pcs a 20mm for each shoes) so it can move.
glue the 2 rods in one holder let it hardened , insert 2 shoes and put a little glue on the end of the steel rots and lock with the other holder. (65 times for each side).
Glue RoadWheels supportArm to the body and glue Track and Road wheels in place.
glue Idler wheels to the Idler Arm ,wait to glue it to the body until the Track is assembled around the wheels so you can tighten it .
There are STL Files if you want to print the rubber foot separately.
all hinges for doors and ramps etc. is printed with a hole in the middle so 1 mm steel rod
can be used as a shaft.
If you want to print it smaller, consider thicknesses, etc. which can becomes very small.
