Gridfinity heat-set insert tip holder

This is a 1x1 gridfinity module designed to hold the cheap sets of heat-set insert tips for the Pinecil/TS100 soldering iron. My particular tips are branded as ‘TOAIOT’. I have provided the STEP file for this design too, so it can easily be modified.

This model has no place to store the shaft that the tips screw on to, as I prefer to use a model such as this to store it with my other soldering iron shafts. 

Since other modules can't be stacked on top of this one, I've used the same flat top design as these gridfinity modules, as well as matching the height so they look good together.
