To better organize Sportident control stations in their transport cases, I designed and built a couple of wooden case inserts. These inserts allow 30 stations to fit in one case while each station has a fixed position that can also be labeled. This makes it very easy to see if any station is missing and if so, which station has disappeared.
This is what the case insert looks like on its own and when fitted into a transport case and equipped with 30 base stations.
I made a drawing with dimensions of the insert. It can be found below in PNG, PDF and DWG format.
