Copper electroforming : Joseph Prusa's buddy

Buddy was delivered with my Prusa Mk2s printer.
I printed it as recommended with PLA at 0.1 resolution.

Then I sanded it a little (probably not enough) and tried to electroform it with copper.

I did follow Jason's excellent tutorial : https://www.thingiverse.com/thing:1661301

and his recipe for electrolitic mixture : distilled water, CUSO4, H2SO4,
