Would somebody here measure (via caliper, much better with a micrometer) the thickness, Inside Diameter, Outside Diameter of a Large CBC slim pad? Help me guys please! 
Just a question, but why would you need to know? If it’s for a yoyo we could tell if it would fit, if your making a yoyo or recessing something you can just silicone it.
I don’t have a worn-out pad
I don’t have a vernier caliper
and I will make a mold of it.
ugh. 
Pour plaster into the recess and make your positive. Coat it with release material, then pour your polymer or resin to make your negative/master mold. Done.
