This listing is specifically for the part of the pottery clamp that fit over the table edge.  This version is modified to fit on tables up to 5.5 inches thick.
 
When ordering your pottery clamp you can order this part at the same time and substitute it for the standard sized part.  Based on the printing time and material needed there is a small price difference.
 
You can also order this part on it's own - perhaps you already have a pottery clamp but want to be able to switch to using a thicker table.
 
Please let me know in the notes when ordering what colour your would like the part to be.  If you are ordering a pottery clamp the default will be to be a colour that matches.  If you are not ordering a pottery clamp at the same time the default will be the marble grey I use most often for my clamps.  If you want a specific colour or to have it match your existing clamp please include a note with your order.
