Shim for Ulanzi Falcam GoPro Mount to DJI Action Mount and TELESIN Magnetic Two-claw mount

When using the Ulanzi Falcam GoPro Mount to DJI Action Mount https://www.ulanzi.com/products/falcam-gopro-mount-to-dji-action-mount-magnetic-base-3234 and TELESIN  Magnetic Two-claw mount https://telesin.cn/products/magnetic-two-claw-adapter-for-dji-action-4 . It is fine for a steady situation like vlogging. 

However, I aim to use this setup on the handlebar on my road bike, there is a gap allowing the GoPro to shake in fore-art movement. this movement can decrease the video quality. so I designed this shim to eliminate the gap.

I printed it in TPU 95A, no support needed, no infill, 4 walls.
