Spray Can Handle Remix

Added in recesses for M4 nuts for easier assembly. Also modified the trigger holes to take M4 instead of M5. Added a small chamfer on one of the overhangs to slightly reduce needed support.

Refer to the original thing for more details. 

Using the https://www.printables.com/model/254654-spray-can-trigger-for-smaller-caps remix fits Rustoleum cans nicely.
