Flipper Zero Case Sleeve

This is an add-on part to compliment the Flipper Zero case published by @Phantom78 here: Flipper Case inc WiFi Dev board - multi colour Remixed by P78 MakerWorld: Download Free 3D Models I really like this case, but I do not use a silicone sleeve so I created this simple sleeve insert to take up the extra space that was left in the original model for a sleeved Flipper Zero. Sharing in case (pun intended) others want to adjust the fitment.
