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.

Created TPU protection for better grip to slippery surfaces
