Robot Lawn Mower by ReP_AL to 200x200mm bed size

Hats off to ReP_Al for his outstanding work. I really wanted to print his stuff, but I needed to print on a 200x200mm bed, so I've started to modify the problematic parts. Some parts aren't identical to the original! I try to sum up the changes and useful information as ReP_Al constantly modified and tuned the parts: - Backplate was split into two pieces; you'll probably need some sanding for a perfect fit. Meanwhile, ReP_Al did a second version of the backplate; my modification is on the older one. Wheel guards come in several versions, I took it from "Higher ground clearance" (https://www.thingiverse.com/thing:3148830). ReP_Al has a newer version making the bearings unnecessary and directly mounting the motors to the wheel guard; I preferred the old one. I've also trimmed the mudguard as this can be only printed in standing position, rotated by 45 degrees. With the mudguard it would have required a lot of supports. I uploaded the baseplate dxf if you want to cut it too. Note that I've deleted a lot of the original holes mainly those which were supposed to hold the printed parts together. So far only these are modified. Also, I don't plan to print the bottom of the mower instead lasercut it from something (see pictures). Bearings you will need: 6204 (20x47x14) ZZ - 2pc for the wheels, 625ZZ - 16x5 (M5) - 8pc for the front wheels/casters.
