I just got this excellent staple gun at a yard sale for 50 cents. Made in Chicago, patents are from 19030s and 40s, haven’t researched it yet. Love the cast grip and cylindrical spring tube up front.
I’m laser cutting a wood veneer to apply to the back of my slightly cracked iPhone back. The starting point for me is the dimension drawings from Apple. You can get them here.
Rather conveniently, the drawing pdf imports into Rhino (the NURBS modeling/drafting application I use) as curves, so I don’t need to trace and redraw the dimensions.
I’m only using the inner curve from the camera back and the camera keep out guide, which recommends the distance from camera lens and flash hole to avoid vignetting or tinting your photos.
