Tank Track, Shocks, Idler Arm, Pins
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This was quite a learning experience. Hard to print and a lot of work to make everything fit. But I dropped a 7 1/2 lbs tank from 24" on to my table several times without breaking anything. May take a couple times making shocks, but they will hold up nicely and give your tank a nice cushion to ride on.
This stuff goes with the Tank Track 2in, Tank Track Idler wheels, worm gear cases, body parts, and lots more in my things.
If you space the Idler arms and shocks 3 inches apart on your tank side rail, you can make your tank as long as you want. All of the parts are spaced so the tank track has a center 1.5 inches from the side rail. 2 inch tank track gives 1/2" clearance to tank side rail.
