I drew this in Fusion 360, you will need some small screws (shaft 2.5mm or less, head 5mm or less) to mount it to the wall.

I first drew the large and small remotes and the placement of the buttons, then offset that and added some nice curves to make the holder shape a little nicer.

I tried inserting magnets to help the remote stay in the holder without having clips to hold it, so that it could be placed and removed without sliding it out, but the magnets weren't strong enough and the remote has very little magnetic material in it so I couldn't get this to work.  
I settled on a design that holds the remote as shown in the pictures, and you can slide it in easily from any end. 

I've found these brilliant as I can use them while they are in the holder, so most of the time I don't bother removing them.

Let me know if any improvements are needed!  The print file doesn't have the version number included, and the .f3d file has the models I sketched up of the remote profiles if you want to use them to make your own holder too.

Print the holder on it's end as shown in the last photo, it will print with no supports

I printed in PETG with 15% infill

I also printed this in resin, with no issue there either, the bottom one is resin and the top is PETG in the photos.
