Included are models of the 3 printed parts in the assembly. The purchased parts (not including desiccant beads) are as follows:
Humidity sensor: https://www.amazon.com/dp/B07GNMKYCZ?psc=1&ref=ppx_pop_dt_b_product_details
Screw Handle O-Ring: https://www.mcmaster.com/9452K142/
Lid radial O-Ring: https://www.mcmaster.com/9452K329/
Bowden tube and fitting that I used: https://www.amazon.com/dp/B07PS3NH82?psc=1&ref=ppx_pop_dt_b_product_details
The o-rings are optional but will prolong the life of the desiccant. Humidity sensor is also optional, I more included it to prove to myself that the drybox was working but it's fun and I like it. If you don't want to use it I suggest modifying the model before printing.
Bowden tube fitting is installed in a self tapping manner. I sealed around it with hot glue just to be thorough.
