Khay Đựng Tiền Cho Ví Kiểu Ridge

I received a ridge-style wallet for Christmas but didn't like the way the money clip felt in my pocket. I took it off, but still wanted to keep some cash on me. So I made this tray to keep the money inside the wallet.

I printed it without top or bottom infill except in the actual tray part, and increased the perimeter count right at the top of the tray for a nicer surface.
