Look at my words on 3D prints , a door speaker frame . $140 odd for two printed in proper full fill print that withstands heat. You will be better off buyin stainless mesh or perforated sheet steel. 3D printing is a scam , its not really but it costs for the material you need for said purpose. Itried to but 10 pairs for all you guys for$ 120 , look what happened….
Get your own setup , buy all the filament , ofeer us cheap stuff…..
