Quick Swap Lipo Battery Tray

This model was designed to allow for quick and easy battery swaps in model aircraft, but has a host of other potential applications.  

The reciever consists of 2 pieces: a base and a catch/lever.  The base has tabs to securely hold the slider in position, and the catch keeps the slider from sliding out until is it depressed.  With the catch in the down position, the battery and slider can be quickly and easily removed.  After sliding a new battery in the base, the catch can be secured to keep the battery from falling out.

The battery slider itself is simple, and unlikely to catch or snag on other materials.  Placing a single battery strap around the middle securely holds the battery in place.  By printing multiple sliders, batteries can be swapped extremely quickly without needing to re-strap to a slider. 

This system was originally designed around a 1300mAh Lipo battery, but the provided .SLDPRT files for each part can be modified for larger batteries or other applications.  The spring system could use further modification to function better, but friction between pieces has thus far never resulted in the battery sliding out on me, even during extended vibrations and harsh crashes.

Other Materials:

-Paperclip (straightened and used for hinge, ends trimmed once properly secured)

- Pen Spring (optional, stiffens the catch/lever used to secure the battery slider in place)

Print Recommendations:

- Print using a stiff material (PLA, PETG, etc.)

- Use supports on the catch and base, smoother surfaces allows for easier swaps
