I printed this on my Thing-O-Matic. The only change I made was to break the handle into two parts so it would fit. I added the rivets to this STL as well.Print out 2x rails and 1x base from the ancestor thing 7860. Print out this handle and rivet sheet. Clean up the handle joint so it fits smoothly. Using super glue or acetone join the handle parts together. Put the rails in the base. Clean up the rivets if needed and snap/glue them into the rails.
