The following is the process behind making my speaker trim and grill.
Before 3D printing I had to re-thread the material through the printer head, ensuring a secure bite.
After removing the base material I sanded down the faces, coated the trim in Polyfilla, rough sanded, coated in Pollyfilla again and then sanded to a smooth finish with a fine grade of wet and dry paper.
I applied two coats of primer and then two coats of silver spray paint.
I used the bottom of a soup pot and a pair of women’s elastic leggings to create the speaker grill. I secured the leggings into place using a cable tie and removed the excess material. I secured the grill with a little super-glue and a glue-gun.
