Lamy Safari Tighter Cap

After my Lamy Safari inked my clothes twice, I searched online and found a solution to making the snap cap tighter. The forum suggested taping the rubber piece inside the cap in order to create a tighter click. It worked but I don't like the idea of using tape to secure something. I created a model to fit around the rubber piece.

The forum post has some good instructions for the disassembly.

Instead of using tape like in the post, just slide the model over the rubber sleeve and put it back together.

P.S. If the cap becomes too tight or is still loose, try slightly scaling it up or down in your slicer.
