The LGX Lite spring conversion files in the linked pintables are pretty good, except there are no STEP files.  Any issues encountered and you will have to modify the files in something like blender. 

There are some issues with the file, all resolvable by drilling and fitting, but the lever does not have the proper offset.  It willl bottom out before there is enough pressure to extrude anything reliably.  TPU is impossible without this.   This FreeCAD parametric model fixes the offset issue.  I have provided the STEP file, that works well for me, it has an offset of 0.65mm.

It is easy to modify the FreeCAD file, even if you are a new user.  You can simply change the VARSET value.  It will re-generate automatically.  The very last feature I just could not get to re-generate without reselecting the fillet.  It is suppressed so the model will not fail, but if you want the fillet, simply reselect the edge.  To export as a STEP file, click on the body then select export.
