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).
If you want to equip your receiverbox with a Blower or carburetor or add a pair of realistic looking headers, visit my homepage!!! 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: https://www.printable-3d-models.com/de/3d-druckvorlagen/3D-druckbares-rc-zubehoer/upgradekits-fuer-die-chevy-smallblock-receiverbox/
12.04.2016: for faster slicing I added all model files as a low polygon version!!! 06.03.2017: theUNDEAD did a remix of the engine block with vent holes for better cooling and increased wall thickness of material surrounding the electric motor. You can find this model here: http://www.thingiverse.com/thing:2153072 !! 01.03.2018: Steven Petrusovski did some modifications to the engine block. He separated the cylinderheads from block, so you have the ability to print the heads in different colors. these files are now part of this database!!! Thank´s for that cool idea, steven!!
