This is a foldable launch pad for drone racing. Its folds to a 20mm thick rectangle for easy storage in your flight bag.

Here is a quick video of a launch: https://www.youtube.com/watch?v=xpBrF1N6wCQ

I used PETG for the final print for better durability.

For the walls and launch tabs, you'll have to print two of them, one of which will have to be mirrored.

Other than the prints, you'll need qty 6 6x3mm rare earth mags, a yard of 3/16th round steel stock, non-slip rubber pads, and epoxy.

I included a .zip folder which has all the .f3d files for remixing/customizing.
