TINKERKIT BRACCIO Robotic Arm Base

I am an Engineering Technology Student from Ohio University. This is a base I designed for the TINKERKIT BRACCIO Robotic Arm. I designed this because the base that came with the kit was made of balsa wood and would easily break or allow the robot to fall over. This base is able to be printed on any 3d printer with a print bed that is 220mm x 220mm in size, for reference I printed this on a Creality Ender 3 v3. This model was made to have a speaker in it; the speaker I used was from an old ihome iBT22. Other speakers may work on this base; the speaker dimensions are 67mm diameter by 4mm deep rim. I would check your speaker dimensions before you print it. If needed, you might be able to design an adapter for your speaker to fit one in where the speaker mounts. You may also need the use some superglue to keep everything connected (base, middle base, top). The holes on the sides of the robot are supersonic sensors; the ones I used are "HC-SR04".
