My son needs braces the upcoming period and, to my surprise, I didn't find any good dental retainer boxes with an insert which could be printed. Therefore I designed this box. It contains:

• The box + the lid itself
• A separate insert with slits to allow water to get out, which allows for quick and easy cleaning
• An optional separate inlay which could be put between the box and the insert, allows water movement between the two.

Let me know if you like it or have any other feedback.
