My Mazda 6 didn't come with any good options for a coin tray. Originally I printed one of these:

I even sprayed it with a bunch of coats of plasti-dip. It worked pretty well... until it fell apart. I realized I had printed it too fast, or with bad filament because it had totally separated layers. :(

I also realized that the coins slid around a bit, so I thought I'd take this opportunity to remix things and design a better holder.

My first design was to take a slanted coin tray like this, but the coins fell and slid around a lot.

The 3rd design was to create sections that would hold just a few coins vertically... but the coins still bumped against each other and would make noise clinking around on a bumpy road.

THEN I had the idea to make a spring-loaded coin dispenser! It took a few iterations, but it ended up exactly like I wanted!!

So, I combined these two "things":
Mazda Coin Tray: https://www.thingiverse.com/thing:1480499
Coin Dispenser: https://www.thingiverse.com/thing:3508659

I also added some slits in the side as "windows" to see how many coins were inside :D

I'm only holding spots for quarters and dimes. I'm not a fan of pennies and nickles, so those can go into the bigger openings until I get home from a trip and empty them out into my desk coin sorter.

My "Thing" is posted here: https://www.thingiverse.com/thing:3661638

Here it is in action:

Reminds me of when I had a paper route and made change when collecting.

Awesome job, Rob! :thumbsup

A few changes I made:
  1. Added about 12mm to the height of the tray
  2. Reduced the width of the tray
  3. Added a "back stop" to the coin dispenser so when putting coins in, they didn't slide through to the other side. Makes one-handed loading MUCH easier.
