Moza SRP-Lite Pedal - Rumble / Feedback Motors

I added some feedback to my Moza SRP-Lite Pedals, using an Arduino and L298N motor driver board all controlled by Simhub

Wiring of thee Arduino and L298N for this purpose can be found with a quick google search. I've attached a wiring drawing I found (only difference is here were using 12v motors and a 12v power source).

I designed some motor casings and a mount for the SRP Lite pedals using the motors available from amazon (Ludom Vibration Motors DC 12V 8500rpm) Link

Designed entirely with Tinkercad

Printed on Elegoo Centuari Carbon with 0.16 fine layer height (due to small tolerances).  Infill was 30% gyroid with 3 walls, and adaptive layer height (set to 30) no supports needed if printed as per the orientation they have been placed in the STL file. 

The two main body pieces hold the motor, with the terminals of the motor at the end with the cable pass through hole.  WARNING! The cables needs to be cut at the correct length for each leg ensuring no slack as a counterweight is just above the terminals (you have been warned). The cable will have no strain protection so it is advisable to use a zip tie around the whole assembly at the end of the build.

Once the motor is wired and the cable passed through the cable hole the two sides can be pushed together, its a snug fit (again mileage may vary with printer tolerances) try to keep the motor vents inline with the vent holes on the side of the case.

The 4 holes at each end of the main body are for 2mm brass inserts, you need to be careful and accurate melting these in. Once these are in you can turn your attention to the base which requires 4 x 3mm brass inserts which should be inserted from the non flat surface (inside the circular recess).

The parts can then be screwed together with M2 screws (M2 X 10 for the base and M2 x 8 for the top) the top and bottom are designed to only go on one way so make sure everything lines up.  

The motor / pedal mount needs 2 x M5 brass inserts to attach to the pedals. The M3 screws required to attach the whole motor case to the pedal mount should be M3 X 10, but it is advised to test fit just the base too the pedal mount and check the screws do not protrude at all the other side due to the spinning counterweight. You may need to cut these down to fit.
