Slot Machine Candy Dispenser (A1 mini compatible)

A new version of my slot machine–candy dispenser (which you can find  here)

I was originally planning to adapt the project to make it printable on the A1 Mini, but in the end, I focused on refining the mechanism instead. I changed the system for unlocking the coin crank—currently, it doesn't differentiate between coins: any coin will activate the machine. The maximum accepted coin size is that of a 2 Euro coin, so for now it can also be used as a piggy bank.

I’ve also eliminated the need for any hardware components, except for the reset spring. However, that can easily be replaced with rubber bands.

I hope these changes help reduce filament usage, cut down printing time, and make the slot machine accessible to anyone—with any printer and without the need for extra hardware.

P.S. I don't like wasting filament, so the wheel is white. I preferred to print the symbols on paper, cut them out, and glue them on. But I’ve included the STEP file of the wheel in case you want to insert your own symbols and print it with an AMS to fully customize it.

HOW DOES IT WORK?

• Insert a coin into the top slot
• Pull and release the lever
• If the wheel stops on the winning symbol, you can press the side button to unlock the candy drawer

BOM (Bill of Materials):

• 0.5 × 5 × 20 mm extension spring (or rubber bands)
• Mason jar (the model fits a 70 mm mason jar, but there's a print profile with adapters for Nutella jars or 60 mm pickle jars. You’ll also find the STEP file for the adapter, so you can modify it to suit your needs)
• Paper and an inkjet printer
