Summary

Oye! Oye!

Brenda the articulated battle tardigrade has been released into the wilds of 3D printing!

Join the Horde to be among the first humanoids to learn about the next epic project from Zheng Labs!

We now return you to your regular model description.

This is a short-stock version of the Zheng3 Penny Ballista designed to be printed on a 120x120mm build surface.

Instructions

Instructions for assembly of the long-stock version can be found at http://zheng3.wordpress.com/2012/05/22/zheng3-penny-ballista/

This ballista will have a slightly shorter range than its parent, but can be printed on a Thing-O-Matic.

EDIT! There's now a model that works with slic3r! There was some nonmanifold geometry around the bow that made slic3r choke but ReplicatorG let through.

I left the original version in place because if it ain't broke, don't fix it. Slic3r users should download zheng3_ballista_thingomatic_slic3r.stl.

If you need a target, try the Seej basic bloxen: http://www.thingiverse.com/thing:23620

Seej is a tabletop wargame based around 3D printing. Check out http://www.s33j.net for rules and more information.

You can also search Thingiverse for Things with the seej tag.

EDIT 6/1/12: There's a new STL that fixes some flipped normals and weird N-gons on the locking keys. If you're having problems printing the previous version, try the clean model. ReplicatorG is pretty forgiving, but other slicing software may be less so.

EDIT 6/30/12: I've uploaded wee_ballista.stl for users still having issues with the size of their build platforms. She ain't pretty, but she should fit.
