I've hacked several toy tanks but always wanted to me able to make my own tank treads for robotics projects.

I played around with several different models but couldn't find much to go on other than picture and diagrams.

I've built in some play and made sure the links should print on a makerbot without any problems (minimum overhang).


This design is untested

2 STLs

Plate 1 = 4 drive sprockets
Plate 2 = 24 Treads links

Print out as many of the sprockets/links as you need and assemble the tracks by using 1mm thick pins (coarse wire)

Nice. What are the toloerances between the treads and the wheels?

Printed a bunch of these. they print and look great. I am building a static model (fictional Mars Rover model for my daughter's science class). I used unbent and trimmed staples to hold the track links together, works very nice and surprisingly strong for my application.

Will the sprockets fit a NEMA 17 motor shaft?

This was mainly a concept design, I've not had the time to go back and attempt to print it out. The SKP file is attached so you should be able to scale/modify if you desire.

This is great. I'll have to print a set.

Brilliant idea for the track. Think that could be used for a printable drive belt for either a Makerbot or RepRap. Some assembly required of course.
