DSLR Grip

I noticed how very ergonomic my Ryobi cordless drill was and adjusted the camera grip to accommodate 2-finger grips and straighter lines for the other fingers.  Right enough - it's much more ergonomic.  Those guys at Ryobi got it right.  Talk about reinventing the wheel!

Also reduced the infill to a constant 20% but with a 4 layer perimeter.  This saves a lot of printing time but is still pretty indestructible.  From 5+ hours down to 3h 46m with a Grid infill.

Also changed the scale from 100.4% to 101%.  This achieves 100% shrinkage compensation for the Prusa recycled filament on my printer.  The camera screw still fits perfectly and the UNC nut still retains friction so it doesn't rattle when off the tripod.

Added a recess for the rubber sheet grip (36 x 26mm inner cycle tube with a hole cut with a paper punch).  Doesn't do much other than reduces the depth of the rubber sheet.  Seems to be just as effective.  You could paint this recess with several layers of latex to achieve the same effect.

Cleaning the UNC nut slot is still a pain but not too difficult with a flat needle file*.

The SolidWorks file is even messier now but if you want to play with the profile you can edit the layer called Grip and Back Shapes under Handle Profile (just below the Origin in the tree).

 *  Bonus tip:  Break off the file end of a spare needle file and grind it down to form a really useful scraper for cleaning plastic parts:

You can use this flat for even scraping (about 5mm) or on its side to scrape 1.25mm slots/parts.  Really useful for plastic kit building and quick-filing of printed parts.
