Hi

Calipers up to about 18" are useful. It is more a matter of what you can afford. Good ones are more expensive. A set of Mittutoyo's at around $120 for an 8 inch-ish set is a good option.

The Nomex felt dimension needs to match up with the spacers you design. Something in the 3/8 to 3/4" range will work.
