TPU PTFE Tube Coupler Plug

In some cases, I wanted to plug a PTFE tube coupler, rather than just the tube itself.  This lets me store a drybox conveniently and without 4 tubes sticking out.  

I printed this using eSun TPU, .015 layer height.  Although the model is correctly sized, I had to scale the print to 105% to fit snugly in my couplers. 

I recommend printing these individually to prevent stringing, and trying 100% or 105% and scaling as needed for your couplers and printer tuning.
