Creator's description
This radio seems to be designed for backpacking, etc - but I'd like to mount it in a vehicle. This bracket attaches to 4 screws on one side of the Xiegu X108G ham radio, and allows you to attach whatever mount you'd like to it. Youtube demo: https://www.youtube.com/watch?v=9FDH6_Xmhuo There is no known commercial equivalent. This mount uses about 22g of PLA filament, for an approximate cost of $0.45. Simple radio mounts for other models cost around $30.
