Aftermarket pads for backpack waist straps

Does anyone have recommendations of pads you can slide over the waist strap of backpacks to make them more comfortable?
I have a BD speed back and the thin waist straps get pretty uncomfortable on longer approaches. I found a single outdoor product one that works perfectly but they wouldn’t sell me an individual pad. 

I'm sure you could find a shoulder strap pad intended for typical travel bags on Amazon that would work.

I’ve looked around a bit but surprisingly couldn’t find any that are short enough (6-7 inches).

I've made a few (photos). PM me if you want to discuss.
