I finally created a systainer rail for my older Festool systainers that have been stacked up on the garage floor for too long. They work great and of course they are way cheaper than buying the Festool brand rails. I used all of my old PETG filament to use it up as you can see they are all different colors. When installing the second one up make sure you use a 3/4" plywood to space it. I used the Festool Sys3 rail dimensions to build the cabinet as you can see their are some sys3 systainers in the picture. I have included two models that are set up for a Prusa mini which is what I have. Just glue (I used clear non-foaming Gorilla glue) the two halves together before installing.
