Mold for fiberglass fuselage
I've been working for some time on a new design for a UAV, the fuselage is going to be made in fiberglass so I printed it in PLA to make a "plug" to create the molds from it. It's actually four parts (one missing on the photos), so I can experiment with different nose sections later on.
To prepare the surface first I used epoxy putty to fill any large surface irregularities, then several coats of primer and finally acrylic paint, lots of sanding and polishing in between and at then end!
The result looks pretty good, perfect shape and mirror like finish.

If I have the time tonight I will start making the fiberglass molds with it.
