About this 3D model

My mom gave me an old broken retro egg poker / egg puncher thing that she have had for 50 years. This is my 3d printable remix on its concept. Use a 15mm Ø8mm spring Cut a 15mm lenght tag/needle Ø.8mm to 1mm. Assembly: 1. put the spring in the "fod" 2. push the needle in the "stift" 3. put the "stift" in the "kop" from the top down 4. put the "kop" and "stift" in the "fod" 5. with a tool (that does not bend the needle) push the "stift" down into the slot in the "fod", press fit.
