500W spindle mount

I thought the aluminium mount for this spindle was too heavy and a bit ugly, and the joining faces against the printed part seemed a weak point. So I designed a slimmer better looking one and printed it out of Carbon Fiber PETG. As my spindle doesn't get hot, 3D printing this mount is ok. I tried cutting some 2mm wall, aluminium box section and it was sturdy enough for the job.
