Spray can handle/trigger

Adding this as it keeps popping up in the comments. The limitations of 3D printing do affect this design. What I mean is a 3D printed part is weak along it's layer lines. When a force runs parallel or along the layer lines, it can easily break the part. I did an example of this by printing hammers in different orientations, than testing them hammering in a nail. When you squeeze the trigger the force runs along the layer lines. This is most likely why people have reported broken triggers. It's a design flaw because of the limitations in 3D printing. I currently don't have the time to try and completely redesign this. Someone has separated the trigger from the main body and posted it as a remix. You can try that, but you do need some hardware.

Edit: I made a Version 2 of the spraycan handle/trigger. I was not thinking of revising it when I put it up, so it's a bit of an after thought.

Someone was wanting a printable handle/trigger for spraycans on a facebook group. I only noticed one of these on thingiverse. I decided to give it a try and this is what I came up with. It prints in one piece and doesn't need support. It pressfits onto the spray cans.
The pros to it are that it's one piece with no hardware or supports needed. The cons are that not a machines handle tolerances the same, so it may not for some. This is why I am including a small test part as well. Print it before printing the full handle. If it fits you have a good chance of the full thing fitting. If it fails than you did not waste as much time or filament printing the full handle Other problems could simply include the joint fusing together.
