This is a coffee table remote holder designed for the Insignia F50 Series Smart Fire TV remote and shorter Fire TV remotes.  It is intended to keep the remote in place when pressing down on the side buttons.  Printed with PLA.

Update: Added a second model with circular spaces for two magnets, but one should be enough.  The magnets are a friction fit, I used a C clamp to get them flush.  Link to the type of magnets used: https://www.walmart.com/ip/Go-Create-Large-Extra-Strength-Magnets-4-Magnets-Total/52828672 

Update: Added model with thicker sides, less likely to have accidental breaks.
