Hello, at the auction last May I purchased a picture framing kit from another member. The kit is missing a crucial part for clamping-up the four corners. It's called a clamp pad. It's red. I'm hoping that person has the missing part in his shop. See photos below.

I dont have access to 3D printer but I can make something that will work. Just one more time waster. I was hoping this jig would save time!
