About this 3D model

I felt obligated to improve and redesign the model. This version fixes all the small problems that the first version had and makes pulling out the PTFE tubes super easy. Additions: +Slimmer. Doesn't collide with the other tubes. +No more slipping off after removing a tube. +Looser fit. Doesn't squeeze the tubes. +Better design with less sharp edges. +Added chamfer as elephant foot compensation
