This is a little Rubber-Band powered quarter dispenser I made to be put into a cup holder of a car to hold quarters. There are catches in the container and on the 2 plungers for the rubber band. I would like to print this eventually, but as of now I do not know if it works well, or if it prints very well.
Thanks, and any suggestions are appreciated, as this is the first thing I have made. If you think you can make it work well, feel free to try to make it, just comment at least so I can learn what I screwed up.
Original file made in Tinkercad here: https://tinkercad.com/things/82BcN5TzLTq
04/28/12-I have now added a version that has been "fixed" in netfabb cloud, so the stl file should print better.
04/29/12- I have made a V2 file that allows the plungers to be inserted through the bottom, then a piece to slide in to cover the bottom. FOR V2 YOU MUST PRINT THE V2 FILE AND THE PLUNGERS (Error in TinkerCAD)
-Fix lip, make sure can print
-Make TinkerCAD work with plungers in V2
All that you really need to do is print it. If some parts are a bit tight, they may require a bit of sanding. To make it work flip the 2 plungers that print with it so their notches are facing down. Then attach rubber bands to them and the ones on the inside and try to insert the plungers. Then just insert in quarters and take them out, perfect for parking meters. :-)
FOR V2 YOU MUST PRINT THE V2 FILE AND THE PLUNGERS (Error in TinkerCAD)- I made it simpler in this version to insert the plungers into the holes, now you can put in the plungers through the bottom. Then simply slide the big flat piece into the hole in the side of the cup so the plungers can't come out. (Thanks PAmes for seeing that with the lip, they can't go in)
