Punch set holder - 6 piece set from Princess Auto

I needed a way to store my Powerfist 6 piece punch set from Princess Auto (https://www.princessauto.com/en/6-pc-pin-and-centre-punch-set/product/PA0008548083). They often go on sale for cheap. I realized that the space I needed was about the same diameter as the original thing, so rather than learn how to properly put threads on a container. I modified the step drill container.

I put an extra hole in the centre (-ish) to minimize material used.

I printed it in PLA with 3 walls, and 25% infill. Which I felt was plenty for a holder. No rafts, No supports.
