A boomerang that I modeled after one that I made from wood.

This is similar to thing:28603, it only has sharper airfoils and I took care that it is about 20 x 20 units in the STL file, which scales easily to the 20cm x 20cm space that the 3D printing company I use offers.


Will work best if scaled to between 20 x 20 and 30 x 30 centimeters and a thickness of about 3.5 to 4.5 millimeters.

Mine has a wingspan of 215 mm and is 3.5 mm thick.

You can greatly enhance wind stability, spin retention, and distance by taping a small coin to the first arm as shown in the photo.

just added on to the made section, ended up in a tree but was good fun while it lasted, printing http://www.thingiverse.com/thing:10188http://www.thingiverse.com/thi... now and hope it will last longer before i put it in another tree


The yellow one is right off the printer from a professional printing company. No manual postprocessing whatsoever.

wow this thing looks pretty sweet. does it come off the printer looking like this, or is there some post printing finishing/clean up?

Update: I had the boomerang printed (on a HP DesignJet, I think) as big as it would go in the 20 cm x 20 cm bounding box of the printer. It's about 3.5 mm thick.

It's kind of smallish for a sports boomerang, but it does fly indeed and you should be able to get some catches out of it. I'd compare it to the kids' models in 3 mm birch plywood that are offered by some boomerang makers.

PS. The narrow racing stripe down the middle was not intentional. I assume it is some sort of rounding error in Blender or in the STL conversion.

Well, it looks good. It's got the curves and slopes right. But the whole thing is only 2cm. I'm half tempted to print it at this size just for the lulz.

Scale it up by 7 and it'll still fit on a replicator platform. By 6 it'll still fit on a printrbot. Theoretically by 5 and it'll fit on a Tantillus.

On second thought I like this scale. Just scale it up for your printer.
