I never quite got into universal remotes. There always seems to be a function that is just not possible with those things.
I created this to neatly stack my remotes on my end table.

Print the items all on one plate. They do snap together but i would apply some super glue on the tabs for extra strength.
The remotes will lay Horizontally in the slots.

I specifically made this to fit my remotes and the slots do vary to fit the different sizes
