Mechanical Vending Machine

I present to you my slightly larger project.It is a simple mechanical vending machine.All parts except the coin selector are printed.In addition to the coin, it is also possible to use a token, which is also in the project.I ordered the coin selector on AliExpress, it is possible to order elsewhere /full internet/ and it can be ordered already set to the desired coins. I ordered for €2 at this address:https://www.aliexpress.com/item/1005006542189581.html?spm=a2g0o.order_list.order_list_main.17.2b3c1802ka2F93I made a drawer for the coins and it can be locked with a simple key, as well as the top lid. I recommend printing the key from stronger material.I printed only the drawer, the key and the balls with the supports. I used instant glue to glue the locks.For reinforcement, I used 2.5 mm self-tapping screws, which I heated before assembly.The machine works perfectly and the children are already choosing their toys in the balls. I use it for tokens that I give out as gifts at the store,
