14500 to 18500 Battery Adapter

14500 Battery Adapter This adapter lets you use a 14500 battery in the 18500 compartment of your device. I use it to fit my 14500 li-ion batteries into my Frsky X-Lite Pro, which takes 18500 batteries but I find 14500s to be cheaper and easier to get. The print quality turned out great without any supports, however I would recommend adding a brim with at least 6 lines if you're not sure about your bed adhesion.
