Have you done any repair work on plastic parts? Any recommendations for filler? Perhaps it's possible to fab up some new endplates for that flap (I'd wager drop-down flaps are like gold-dust; they always break or go missing).
No, I haven't ever tried to do "body work" on plastic parts yet. I've drilled/cut holes for LED's and connectors and that's it. I do have something that needs some filler-repair though, and since I've done construction, I've used this Elmer's brand wood putty that is actually some type of polymer plastic and I was going to try that with some light sanding and a few coats of paint. See if it works good for plastic. It comes as a standard paste that you scoop a bit out and whipe it over the hole or broken area, let dry and finish. Only an hour drying time IIRC.
BUT, for a cracked or broken part that needs to fit together and be strong, you need JB WELD. Sold at any hardware store, this stuff is metal-strength rosin and once dry, can also be sanded and painted. The stuff comes in two separate black and white tubes and you mix it to grey, apply and let dry overnight (at least 8 hours). But it's runny stuff, so it's not the best in every situation. (some masking tape can hold it in place while drying)
