This model is meant to be a sled for the Featherweight Altimeters Blue Raven, Power Perch, & GPS Tracker (links below) that can easily be removed from your rocket with all components still attached. It is designed to use the same hardware sizes as what ships with the Featherweight components and the wood “flap” is the one provided by the Power Perch kit.
I have been using PLA to print these and have yet to have any issues.
