Quadcopter extension plate/ TBS Discovery

This is an extension plate I made to turn my cheap 20 bucks reptile frame from ebay in to a "TBS discovery" like frame and also to balace my aircraft for a 4000 4s battery.

There is a Top plate, Bottom Plate and an Camera plate.
You will need to change the screws for M2.5 x 10mm on the frame because the plates are 4mm tick and I printed them with 20% infill.

Thank you.

Any feedback will be great.
