Do you remember ViewMaster?

I used 10mm x 1mm magnets I've rendered it down into stl's for a few different sizes, but here's a link to the CAD for the model: https://cad.onshape.com/documents/24e9bd9be2daad946e164ba8/w/9aeec83eec42d774c1886809/e/5b7e9405784cfe0741b6bf4d?renderMode=0&uiState=6449ac24331d906b56ef90a9 I was careful to make it easily modifyable just by changing a few parameters: 1. The number of slots (how many reels it holds) 2. Size of the magnets used.
