union faces of a solid

[flavius27]

Hello everyone,
After working days I managed to rebuild a solid from a 3d scan, now I wondered if it was possible to gather the numerous faces, with which it was rebuilt, in a more exiguous number.
Thank you in advance.

p.s. for those interested here is the file https:/www.dropbox.com/s/ykwytmlqfz1h9m0/ce l'ho c.sldprt?dl=0
