Doesn't Matter

4 x motor brackets are needed one for each of the motors. These should be attached using screws and nuts.

The Raspberry Pi should be mounted using PCB stand-offs

The optional top layer allows for a two layer chassis. 4 x spacers are required which should have threaded inserts (sometimes known as knurled nuts) which can be melted into the end of the spacer.

The ultrasonic distance sensor mount can be mounted to the front of the chassis using screws and nuts. Due to the small size of the PCB screw holes these are not included, some adhesive tape or adhesive putty can be used to hold the sensor in place if required.

Original FreeCAD file is included.
