Tri-bladed boomerang for recreational throwing. The print is intended to be 200 mm wide and about 178 mm high, at a thickness of 3.5 mm. Other dimensions may work, but your mileage may vary.
The 4mm holes are intended to be filled with metal; the additional weight will help with spin retention and distance.
I put pieces of 4mm copper rivet into the holes and peened those a little so they stretched outwards and stayed put. Another possibility would be to screw in pieces of M5 thread, which has a core diameter of just about 4 mm and should fit nicely.
Depending on the resolution of your print, it may be helpful to smooth the surface a little. I use a card scraper for this.
There are two STL files. One is called LEFTY_... - that one is needed for left-handed throwers, which need their boomerangs to be mirror images of the right-handed versions. Everybody else can ignore the "lefty" file and use the other one.
PS. The strange spots around the holes in the rendered picture are shading artifacts from Blender. The model itself should be ok.
