Screw coin wallet (support free)

thingiverse

This is a bit more than a simple remix, I took only idea from the previous design because I liked the idea and I was thinking to do something similar for me. In my design bottom part of the wallet reinforced because I had two original wallets that were broken, thread modified to be printed better and to have better adjustement, spring added to prevent the coins fall out from the wallet, this spring create a slight pressure on the nut a don't allow it to unscrew easily. All parts can be printed without supports. Some art designs added. If adjustement between base and nut are too tight you may try nut with bigger gaps. I would suggest to print the spring from PETG because it's more elastic, but PLA will work as well. As always any comments, suggestions and feedbacks are highly appreciated!
