coin mechanism for candy / toy vending machine

I have been asked several times whether it would be possible to invent a coin mechanism that can be pressed into a 3D printer, so I tried.
I tried to make it so that it would fit in place of the original mechanism and could also be replaced in previous projects.
I think I succeeded quite a bit, but I have a problem with the part for checking the presence of a coin, which needs to be printed from a stronger material, so I recommend leaving it out completely, even if the mechanism will rotate even without a coin.

If someone manages to modify it and make it a little different,
I will be happy to do so. For now, I recommend leaving out the red part in pictures 8 - 12

I used coins and tokens in the size of 2€, it's all about the size,
so it can be modified to other sizes.

my older project:

and the bigger one is here:

I used M2x6, M2x8, M2x10 screws

Assembly procedure:

1- put the coin carrier on the shaft
2,3 - insert it all into the case
4 - add a washer
5 - secure with a cotter pin
6 - we can connect the control knob
7-13 glue the flexible part - red in
the picture and screw it to the back cover.
I recommend printing it out of a solid material,
because it is very stressed. I didn't have that option,
so I ended up leaving out the red part.
This part holds the mechanism until a coin/token is inserted and won't let us spin.
If someone uses more force, this part will break off,
so it is advisable to print it out of a solid material,
or leave it out completely like I did.
However, the mechanism will then spin even without a coin.
14-15 screw the stops
16 - we can screw the whole thing together and insert the cotter pin on the shaft.
17 - insert the bevel gear
18,19 - add the washer
20 - the upper gear
21 secure with the stop washer and screw
screw the whole thing together and insert it into the machine, instead of the original metal movement.
