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

https://www.printables.com/model/166851-tank-tool

A small tool for opening atomizers tanks (RTA, RBA) or even drippers (RDA).

Important note:

Print solid (100% infill), with somewhat thick walls.

This pocket friendly tool is a wrench for opening stubborn tank atomizers. It is dimensioned for 22 mm tanks, but it works with 23 mm atomizers as well. I suggest that you print two copies, and use them in conjunction.

If you want to make a tank tool in a different size, you can adjust the scale of the X and Y axes to the following percentage before you print:
23 mm atomizers = 105%.
18 mm atomizers = 82%.
16 mm atomizers = 73%.
14 mm atomizers = 64%.

You can increase the Z axis scale for a more durabIe tool, but keep in mind that overdoing it will make the tool awkwardly rigid.
