M.A.X. Truck - The Modular Toy Truck - Base Vehicle

Mission Accessories eXtreme!

28 Nov 2020 Update - Replaced the side windows with a better fitting (taller) .stl.

25 August 2019 Update - I've added a "DriveWheelV2". This is just 1mm narrower than the original drive wheel that is still available. I find this one spins more freely, and is what I'd recommend you use. I've also found that a little bit of silicone lubricant on the axles (like you would use for workout equipment such as treadmills) makes a HUGE difference/improvement. I actually applied the lubricant after assembly by just squirting it into the gap between the wheel and axle. Spin the wheels to distribute the lubricant after application, wipe away the excess, let sit for a day to let the fumes dissipate and ensure no dripping.

This toy truck has a steerable front axle and a rail system on the back to slide on multiple accessories for different missions. The front bumper includes slots for front mounted accessories. Windows can also be printed in a variety of colors, and simply pressed into the slots in the main truck body, to be held in by friction (fit may vary by printer / print orientation).

The base vehicle posted here includes a fifth wheel for a trailer that's being designed.

I do plan to post the dimensions for the rail mount system so other can develop their own accessories.

I've also created a shorty version of this truck: https://www.thingiverse.com/thing:4383776

The only extra material required for assembly is assorted M3 screws. Use M3 x 20 screws on the steering axles to ensure sufficient strength. Be aware that there is a slight recess in the steering axle to accommodate the head of the screw. Use M3 X 8 screws to hold on the aft bottom plate. Use M3 x 6 screws to secure the forward bottom plate. Use an M3 x 12 screw for the center hole in the steering tie bar and top steering tie bar.

This design was inspired by and dedicated to my newborn son.
