Retro Boomerang with Wide Wings

This is a variation of my very first boomerang design dating back all the way to 2011.

I made the wings a little wider, added slots to slow down rotation towards the end of the flight, and added an optional center hole for easy one-finger catches.

Notes:

Make sure your print lays flat on a table when you pop it off the build plate. Mine usually warp downwards a little, which needs to be corrected. To fix that issue, I warm up my print slightly (on the build plate, over a toaster, or with a hairdryer), and clamp it to a flat surface with the wingtips slightly elevated on top of coins or small washers.
