I wanted to replace my low profile wall mounted contact holder, that only holds a weeks worth of contacts with something that could hold a lot more, so I found the largest holder and made it bigger.

From the bigger version I made 3 types and adjusted for less material at the bottom:

• Wall Mounted version
• Regular Version with support for sitting on a surface
• Wall Mounted w flared top to make it easier to pour in contacts

I maintained these to not need support but if you have issues with bed adhesion, a sling type bed or just want more stability, you might want to use a large brim
