This is the conversion of an idea from user Klampykixx.
I´ve converted the "V8 receiverbox" to hide your 540 style electric motor of your R/C car, now!
This database contains only the parts which are different to the "V8 receicerbox", so all accessories for the engine can be used from the "V8 receiverbox".

This model will work with standard or modified 540 engines (35,8 mm diameter, 50mm lenght). I applied openings for the power cables in front of engine block.
Maybe some modifications are necessary after printing (depending on electric motor).

The last two pictures shows some Upgrades for the Engine Block. They are not a part of this database, but you can get these parts on my homepage:
