Inner Doorlock Knob

Our Campervan is a Mercedes 207 D built in 1980. The doors can normally be locked from the inside by using a red knob. Unfortunately only one of these knobs was left in our van and they are pretty hard to get. So I took the one I had, used a calliper and designed the part for my needs in Fusion360. It is slightly bigger than the original part but it fits nicely and we finally can lock all doors again :)

I used M5 30 metalscrews to connect the knobs with the locks.
