Enclosure for the Car Cup Holder Coin Sorter Caddy

I liked the Car Cup Holder Coin Sorter Caddy by @MatthewFuhr_856292, so I decided to make an enclosure for it.

No locking mechanism for the top and sleeve, considering one, what do you think? Comment and let me know.  When the caddy is loaded with change, the sleeve holds pretty well. 

Please share your makes. Thanks!

Printed with 15% infill and no supports, with PLA haven't tried PETG.
