Do you mean, add an idler to be able to use a longer belt? I could do
htat I suppose. The real problem is the belt material, mylar. It's not
easy to fabricate stuff out of thin mylar, especially in these
dimensions and tolerances.

It needs to be low compliance, eg. not stretch, it's in a servo loop,
and a rubber belt would likely make the servo loop oscillate.
