Designed this for an etrike project and needed a mount for the 6.5" hoverboard hub motor I was using.

This was printed at 80% infill with 2mm sidewall and top/bottom, with petg printed with side down. This might be overkill and you might be able to do a little less infill but I needed the extra strength.

This was snap fit tight over my hoverboard hub motor shaft.

Bolt holes are for 9.5mm (3/8") bolts with 9.5mm (3/8") ID x 22mm OD washers
Since its printed on its side the bolt holes were a little tight.
