About this 3D model

EDIT: Please note this design is included in my new complete repair kit available here: http://www.thingiverse.com/thing:893318 Started to renovate a couple of old Bang & Olufsen Beovox CX100's, but did not want to discard the old fronts in case something went wrong or looked weird. I replaced the original fronts with these I printed and fitted to the speakers wrapped with flexible jersey material bought at a local fabric shop.
