Sinistral Fault with inclined markerbed

A simple block model showing a sinistral fault. It has a removable core for stimulating additional discussions during the class. We use them in our GEOL101 labs and Geological Field Techniques classes. This is one of eight models used by students during a GEOL 101 structural geology laboratory.

These models would typically require the use of a dual-extrusion printer and can be printed in a variety of materials. PLA has been our choice and has worked well for us. The dual-extruder printer files folder contains six .stl files. The marker bed and body files (top&bottom) can be merged in the printing software and get assigned different colors. The drill core model gets printed separately. Remember to have it match the filament color of the fault body model.

It is of course also possible to print the pieces individually and glue them together as well! The second folder, named “single-extruder printer files”, contains each of the pieces that can be printed separately.
