Designed in fusion 360. this is portafilter handle for La Pavoni pre mil. fit perfect for M12 size handle. the final print itself will not make perfect fit to the M12 handle. you will have to tap it with M12.
In the sample picture above, I used the vertigo PLA and brass fill filament. I sanded down with 220 grit paper and polish with simichrome on cloth to make it shiny.
