The file 'Filament Straightener 2 Axis 3D Printer Model' is (SLDPRT,STEP,STL,SLDASM,7z) file type, size is 1.6MB.
This is just another filament straightener, a straight filament creates less friction in the bowden tube. It also enables you to make use of those last turns of filament that are tightly coiled around the center of the spool.
To assemble you will need a 3.3mm drill and a M4 threading tool, the drill is used to clean the holes before threading. When I do the threading I soak the parts in water to give lubrication and cooling, don’t thread to fast it might cause the plastic to melt and destroy the threads. On the deep threads retract the tool when you are halfway down to remove waste before you continue the last part.
I bought the parts on eBay, I won’t update the links when they become obsolete but it’s not too hard to find similar items:
