Woodturning - Rotary Bowl Sander Marius Hornberger style - M10 Version

Technically this is a remix, but there are not yet printable files available as far as I know. Marius Hornberger (See Youtube) designed a rotary bowl sander to be made from wood. This one had worked very well for me, but I wanted to improve it a bit and mostly downsize it as far as possible, as my wooden version was quite bulky.
The original plans can be seen on his website: https://mariushornberger.com/de/collections/free-stuff

I designed mine for some flanged igus-bearings because I had them on hand, they now also use a 10 mm shaft. There is also an Update for 608 rollerskate bearings: https://www.printables.com/model/528831-woodturning-rotary-bowl-sander-for-608-bearings-m8

The bearing housing prints flat on the bed, you might want to try and reinforce the area underneath the wingnut as i had to use a very big washer to not crush it while tightening it, even though I used a good amount of infill and perimeters. Also some supports for the lower ledge of the flanged bearing would have been nice in my print.
Sanding pad: the front is 47mm wide to fit my interface pads. I glued on the velcro as in the original with concact adhesive after roughing up the glueing surfaces. The prints needs a print pause after the space for the nut is fully printed to insert the nut. I also printed infill first, then perimeters, as the “overhang” over the nut enclosure would not really be printable otherwise.

For material, PLA seems sufficient. 

Also note the handle with attachment for a vacuum cleaner:
