Since this model needs support I think PLA is the best option. Supports seem to come off the best with PLA and it is plenty strong for this application. I used Snug supports "off the bed only"  for all the parts except no support needed for the trigger or the wheel. I did not fill the bolt holes with support and it seemed to work fine. You can see the print orientations I used  in the .3mf files. 2 walls, 15% fill, full speed input shaper.

Hardware:
4x 50mm m6bolts 
5x m6 nuts
1x 80mm m6 carriage bolt and wing nut (added the extra nut as a locker)

The printed handle secures with an m8 or 5/16" bolt , 1.5" long. This bolts threads into the plastic of the main body.
