The coin slider only goes in one direction because I was having trouble aligning the circles to make it interchangeable.
The stick glues into the draft engrave.
1/8 inch wood used.
It is pretty cool. 
If you make it please post a photo!

Oh cool! I love those disappearing coin trick boxes! 
It took a few revisions to get it right! Started by making 2 boxes at
https://www.festi.info/boxes.py/UniversalBox?language=en
This website is so much better than the iphone app which uses outside of the box measurements and was driving me insane…
Revising this to make sense… tired and can’t string a sentence together.
I had one of these, similar anyway. What fun! Thanks!
Thanks. These tricks are fun.
If you change the render parameter in the output url, it will convert it back to an editable form!
My son gets a real kick out of it, we brought it to a fundraiser garage sale today and gave it away as a way of turning pennies into quarters. 
@bkressley mahalo!
I’m not sure how to do this. When I saved it as an SVG it was throwing an error that was not corrected by copying and pasting it to a new document.
So fun!!! I had one growing up! Need to make these!
I fixed the svg and attached it as a zip…
Awesome. Thanks. I was just letting you know that it was an option. I find it very convenient to be able to adjust the setting for one option, then to have to enter all over again.
Works like a charm. Only issue I had was I wasn’t paying attention, and the Pineapple was set to cut instead of engrave… luckily, I only had to recut that one piece. Thanks for this, my girls will love this!
Awesome!!! Thank you for posting the photo!!! 
sweet, thanks for the file. plan on making a few of these.
Have fun with them! We are having a blast with ours. Sanded the wood with 600 grit and it just feels amazing.
Love it! Thanks for the share - now who shall I make this for…
Very cool puzzle, thanks for the share!
Thank you for sharing good stocking stuffier
