I have migrated to Printables because of the security and UX issues here at Thingiverse. You can find this model here:

Updated, new version: The Steam Engine tank tool.

Inspired by the Kayfun 4, this tool gives you a grip on your 22 or 23 mm atomizer.

• Never have a stuck atty again.
• Never unscrew the wrong part.

An older version of this design was copied and sold by multiple companies, both in the USA and in China, who claimed it to be their own design. At least the various Chinese manufacturers showed some collective creativity by adding some tweezer (twizer) thingys to the ends of the wrench handles.

Well, let them all have their inferior product. The elegant version 4.5 surpasses the old version by a mile.

• It grips the atomizer better.
• It is more ergonomic.
• It is stronger.
• It is lighter.
• It is easier to print.
• It looks better.

I could go on (or could I?), but you get the point.

Download this thing. Print at least two. If you print two hundred, be sure to give away a bunch for free.

And never feel the urge to curse at your atty again (or cry in the shower for that matter).
