Walther PDP Spring Installation Tool

After fighting once or twice with my newly acquired ZRT (uncaptured) 15# spring and high mass rod, I decided I could probably simplify the install with a simple tool. A half hour of modeling and an hour of printing later I present the SpringAssist. Note that this is for a 5" slide on a standard PDP(-C). I don't know if it will fit an F or a 4" slide; I'm expecting it won't. If I get the dimensions for other models in the future I'll add them.

Printing tips: this has been modeled "upside down" so you'll need to flip it 180 degrees to print on the bed properly, no supports are required. Due to the small contact area there are three "ears" added for better adhesion which can be easily clipped off after printing. I recommend printing with 5 perimeters so that the assembly is solid; it's so small there's no need to economize with infill. Any material will work.
