Movement Trays

A lot of my friends wargame and are always telling me about the awesome laser cut scenery that is available, because I don't wargame I don't have the time to make these things so it's nice to finally be able to help them with something. 

Here is a pattern for a basic movement tray. I looked into making some parametric design script but actually it's just easier to change the sizes in inkscape directly. It's a simple 2 layer, 2mm mdf, construction with the second layer forming a 3mm lip around the tray which stops the edges units from falling off the tray (svg here)
