Powered Triple Gear with Triangle Box Stand

This is a remix of the Triple Gear by henryseg, designed to have a cool triangular stand containing batteries and a motor. The motors used for the project were gotten for free from my makerspace, which turned out to be these from pololu, and it can be easily modified to connect to another motor, by modifying/replacing the "Hackerlab_motor_connector_to_tri_gear" files with one of your choice.

Pre-Assembly and Materials

You need a bit of superglue (other glues likely also work) to attach the motor connector to the axle (or scale the connector down slightly for a friction fit). I used a 2 cell AA box from this project https://www.thingiverse.com/thing:941081 set up in series, though you can use a power supply better suited to your motor (I recommend experimenting with a variable supply if possible, you likely want a slower speed than the motor is at it's rated voltage). I also recommend using a power switch, soldered between the battery box and motor. rnGlue the motor to the Motor Holder piece, you may need to modify it to fit your motor, and have the axle in the center. I used hot glue for this step, but other glues should work.rn

Final assembly

Put the battery box and switch into the triangular box, putting the motor holder assembly in after it, as the motor is running (you may want to verify the fit before turning on the motor, but will need to disassemble to this step to access the power switch). Then fit the axle and motor connector assembly onto the spinning motor. on top of these put the baseplate, which should sit on a narrowing of the connector. Then fit the triangular lid on top, so the baseplate fits through the holes, and is stopped from spinning by the lid's tabs. then simply put the triple gear on the axle, it should spin freely (once all support material from printing the gears is removed) sitting on the baseplate.

Finishing touches

To reduce the rattling of the box, you can put a dab of hot glue on the corners of the box lid (but don't reattach it until the glue is dry), and on the edge of the tabs that the baseplate spins against. This cushions the rattling of the plastic. You may also wish to modify the design so the power switch can be accessed from outside the box. If not, it can be easily disassembled to get to the power switch when you wish to turn it on or off.

I designed the box to contain the electronics and to turn the gears from the motor's power.
