Updates coming soon!

The chassis is sculpted out in one piece ( large build plate needed! 280 x 250 ) , which gives maximum strength 💪 , and less weight, much less screws needed, and makes it cheaper to build. For the maximum performance I recommend to use Easy PA  filament.    The greatest challenge is whith a 3D printed chassis are the impact resistance. I crashed many times to find all the week points, and improved strenght where it was necessary. Fixed problems: 1. Weight reduction,  2. Suspension arms hinges strenght, 3. Chassis  owerall strenght, 4. reduced printing times and less material necessary. 5. Improved power consumption efficiency, by minimising frictions and by adjustable belt tensioners. 6. Easy maitenance, 7. Enclosure for protecting from dirt and stones.
