Ottoky is a good design and good looking robot, but you missed something here. You need to make your body smaller to fit the Toky maker.

Are you planning on using a bec or ubec to protect the voltage from the lipo?

I only have step files, which can be tricky to work on in inventor due to ratios.

If I put the maker here, like I think you meant to do, then you must cutout the bottom. There is no room for the dupont 90 degree header pins. You must allow 3 mm on each side for the pins.

Before I print this as a toy model at 40% please let me know how you plan to proceed.
Thank you
