This is already my 7th version as I took some time to refine the rail and close lid clasps but I prefer it this way.
It is quite a tight fit which should eliminate all the wobbliness.
Should the lid turn out to be too easy to take-off and require some tweaks, I will post the updated version.
The author remixed this model.
Main difference between this version and the original is that the rail where the controller slides is remade from scratch and smooth all the way (original was not), additionally my model has a “floor” with a hole enabling easier retrieval (original is hollow) and includes a lid.
