Cable / pipe / hose channel for walls

thingiverse

I designed a pipe that fits into a hole, capped on both ends to keep foreign matter and moisture out of a confined space. The idea came up when I was routing compressed hoses through a wall, wanting to prevent moisture and possibly pests from moving from inside the wall to outside or vice versa. At its maximum capacity, this model is tailored for a 23mm diameter hole and a 121mm length between two outer walls. However, due to the protruding lock nubs beyond the 23mm diameter, it's best suited for drywall where you can force it through. I suggest printing the cap at a slightly higher scale than the body depending on your printer's precision level. Since this design has room for improvement, I've included an RSDoc file if anyone wants to start optimizing it right away.
