Piranha Plant Candy Dispenser - Super Mario Pipe

Remember the last time your Mario was bit by one of these carnivorous plants coming out of a pipe? Times have changed and now they give you sweets (but for a modest price)!

The approximate size is 21x19x43cm for the standard version.

-------------------------------------

UPDATE (25/05/2025): I've added two parts to make this model A1 MINI COMPATIBLE. The adapted PIPE has a thinner upper side (1.2cm less in diameter) and the adapted BODY simply removes the final “shelf” where the candy falls. So, without having to sacrifice much, the design is now compatible with the 18x18cm build plate! It has also been reflected (and warned) in the assembly instructions.

Also note that the filament consumption for Brown and Dark Green appears doubled in the profile - the actual consumption is half of that value as I included both bodies and both pipes (A1/A1 mini) in the same profile.

-------------------------------------

No AMS is needed to print the model, as all parts are single color. Refer to the assembly guide for details, but take into account that there is a coin locker that needs to be properly adjusted in order to make this work. The candy size is also relevant; the “square” ones I used for testing, work but might give some problems as they can get stuck in some cases. Round candies should have no issue. There are also different sized holed gears to adjust to different candy sizes, so choose wisely and test it! 

I used PETG for the mechanical parts, but it shouldn't be necessary. Otherwise, it is pure PLA. I also added a magnet to keep the plant soil attached to the candy cover, but it is not needed either, so you can either do as I did or just skip/remove the pause. Other than that, I think 17 M3 threaded inserts and the corresponding 17 screws (mostly short, 6-8mm, but three of them are a bit longer, around 16-18mm). Pretty basic stuff in this regard.

All coins around 22mm diameter and thicker than 2mm should work. In any case, I added a Mario Coin design that you can clone as many times as you wish and it fits the machine.

Listen to the satisfying sounds in the actual video and enjoy!
