TPU Sleeve for Jumbo Clamp

Squinn's Clamp is amazing and i already have a few printed. However, the flat inside of the clamp was too slippery and the clamp would slide off the table if any lateral force was applied. By adding A TPU layer the grip is now much stronger against lateral movement/bumps. For more grip I scuffed up the flat side of the TPU with 120grit sandpaper. DIdn't do any tests to see if that helped or not. Either way the grip is pretty strong now.
