Hi, I am 3d printing the STLs for the Revolution6. I have 12 HDD servos on order, due in March. In the meantime I have to hand the Developer Kit which has HD servos. These do not seem to fit the EZ bit P23 A-01 STL as supplied in the Revolution6 assembly tutorial. Are they a different size to the HDD servos. Or could I be missing something in how to attach the servo to the printed part?
