I noticed some parasitic drain on the battery of my Leaf Blaster when the remote was switched off and not in use. To resolve this, I installed a simple switch (purchased from AliExpress) to disconnect the battery when the device is not being used. Please remember to reconnect the battery before charging.
The case was printed in TPU 68D, providing stiffness with a slight degree of flexibility. The switch can be inserted from the side and then rotated into position.
The author remixed this model.
I modified the original file by adding a small notch to allow the switch to seat securely without requiring glue.
