I took the basic design and hollowed the cup out so you can put batteries and wiring inside. I added holes at the top for LED lights. I created interlocking bottom and middle so you can open and replace batteries in the future.
I accidentally created the original with reverse locking so its right to loosen and left to tighten. This isn't a major issue since you don't need to open it often. Sorry!
The print is pretty big. each piece takes 5-20 hours depending on how fast and quality you want to print. Since its a pretty big object with not much fine detail you can get away with a lower quality for faster speed without effecting the print much.
The top piece i found printed better since it had less overhangs if you did it upside down. I had started making this out of ABS and switched to PLA half way through so i had to paint over it.
I choose blue and white lights to represent my home team Winnipeg jets. You can change it to what ever color you want. Go Jets Go!
The base I printed with a higher infill % (maybe 50%?) because it was small and has a lot more fragile parts compared to the rest of the pieces.. The middle and top is pretty easy for the printer to make so you can get away with 20% or around there.
Its pretty basic stuff except for the wiring. I used this guide to figure out what I needed to do.
The base and middle spin&lock together so no assembly required there The top needs to be glued onto the middle piece.
I glued 2 packs of battery holders together to make a 4xAA pack. I attached the packs so the wires are in series to make it a 12v circuit. These 2 fit into the box on the base so they don't tip over and shake around the cup. This provides a stable and low center of gravity. The toggle switch for the LEDs is facing the bottom of the base so it doesn't ruin the look of the design. The wires run up to the LEDs that face the top of the cup.
Each LED has a resistor on the Positive end (red). A wire from the switch runs up to the LEDs and connects to all LEDs in a parallel circuit. Same goes for the Negative (black) ends. A single black wire from the switch runs up and connects to all of the negative ends. This means all 6 LEDs are getting the same amount of power so they are all the same brightness.
