2) select desired diameter
3) choose length (1, 2 and 3 stands for short, medium, long)
4) toggle collar (see the difference in real time)
5) check parameters written within 3D space

This wall plug is best fitting to solid materials, such as solid bricks or concrete. Disclaimer: Use on your own risk, as this fastener has no official certificates. Experiment with low loads first, please.

There is no need to download STL file, you can have all of them online whenever you want :-)
The design was scripted with love in Grasshopper for Rhino3D.
