Printable ear for My Little Pony Cosplay. Can be left as bare plastic but looks far better when covered in felt. You will need a mirror image for the opposite ear, I have a 60cm hat sized head so some scaling may be required to get it to fit properly on others.
If you do use these for a costume please let me know because I would love to know how they turn out.
Rafting up to 20 degree slopes is highly recommended, as is a brim of at least 20mm to provide plenty of adhesion to the bed. I printed mine upside-down, so tip at the bed of the printer. This may not be the best way but it was satisfactory.
I used Colourfabb XT for my print, I do not know how well other filaments will perform.
I covered my ears in felt using fiber-glassing epoxy resin. Then sewed them into the wig.
This is somewhat of a mess of solidworks surface modelling. I retain the original files should other types of ear be desired (bat ponies etc.)
