I don't like Coroplast for wing fins so I decided to print mine. I used ABS on a 100 degree c bed with PEI covered with glue stick. An easy way out would be to use PETG. PLA is not great long term in sunlight. If you're having trouble with the fins warping after taking them off the bed, use a covering iron on high (for ABS) and slide it over the concave side of the warp. After a little experimentation you'll learn how to get it flat.
The big fin just BARELY fits on the bed (see the photo) so
