Stuck Zippo Insert Unsticker

I got a very stuck insert in a used zippo lighter. I tried all the standard tricks and ended up modeling this jig to fit around the insert. Holding the insert with a screwdriver through the chimney, the case can be pushed off from the top. Or go full send like I did and whack it with a rubber mallet. If your insert has a different thickness, you should be able to scale in any direction as needed.
