Bruder CAT servo skid plate
thingiverse
The only file that was missing in the original conversion kit was the floor-plate. Use this plate to fixate the 4 servos and attach the original wheel with the wheel adaptors. Grind some parts of the original bottom plate of the cat, and glue/fixate/screw/... this plate with the 4servos on the original plate. The plate is foreseen for 4 MG90s servos that are available at aliexpress for just a few dollars. printsettings are irrelevant, but 35% infill doesn't sound overkill. Mixing the servos might be a whole other challenge... keep in mind that most cat's actually have counter-rotating wheels at the inner side when turning... (Most traditional transmitters don't allow the amount of mixes required for thatà
