This holds 14 pairs or 2 weeks worth of contacts. The bottom is tall enough to grab one pair of contacts at a time, the windows allow you to see how many contacts are left, and the small bumps on the inside assist the contacts in staying horizontal.
For the contacts to stay horizontal, I recommend that the heavier part (part with the contacts) be towards you and the lip be towards the wall.
I have also uploaded the .f3d file so if your contacts are of different dimensions it can be edited for your needs.
