Double PTFE Tube Lock

I wanted my PTFE tube from the printer to stay still while I ran my PTFE tube from the filament dryer directly from it to the printer, and this would prevent the tube from the printer from being jammed. Also, this is very useful to swap between two filaments quickly without changing spools (you need to leave the filament in the original tube for the run-out-of-filament sensor to not activate). btw the tube is like 4.17mm
