Replace lost or worn pads for your Irwin Quick-Grip clamp with your own 3d printed version. This is where I wish I could print flexible filament on my printer. If necessary, glue 80-grit sandpaper onto the faces to prevent slipping.
Create specialty clamp pads with v-grooves to hold round pieces as shown in the picture. They make cutting a pipe or dowel a lot easier.
