If you want the top of the remote to be flush with the block, aim for the sum of your stock heights to be about 24mm (1inch).
There are two profiles to save time/waste. You could cut this out of one solid piece, but you’re going to make a lot of dust. If you use similar materials/settings, expect to cut both parts in about 30-45 minutes.
Originally I was going to secure the profiles with some glue + dowels, but I got lazy. There’s a decent chance tomorrow the dog will have eaten both the new remote and the holder anyway. So I just sparingly used a little bit of clear gorilla glue, then clamped, waited and sanded everything.
