Sanding Block (1/4-20 Bolt + Nut) no supports

Sanding Block designed to hold sand paper. 

Required Hardware:

• ¼-20 nut
• 1 inch long ¼-20 bolt

No supports needed. 

Parts are already oriented correctly. Check supplied reference picture when slicing.

I printed mine on a Prusa MK2 with the following settings:

• layer height:               .35mm
• perimeters:                 2
• infill:                            20%
• infill type:                   cubic
• top/bottom layers:    3
• Supports:                    off
• Bridging                      on

More perimeters and higher infill will make a stronger print, but the above has worked well for me.

Please post pics of your print and let me know if it works for you.
