I saw the original version and while it would work for my needs, I wanted it slightly different.

I added some extra material where the filament enters. Its only a matter of time before a simple hole like was used would wear down so I added a bit more material to make it take longer. You could also drill it out and add some PTFE tubing in and the extra material would just give it some extra support. Another thing with the original was that it was designed to remove the support for the flex tube. I didn't like that so I made a slight adjustment so that it should work with that support in place and actually use that support as a method of locking in place.

I also removed the original creator, DinkyMods logo from the top. While I get the idea behind wanting to put a logo on things you make, my mentality is "why make it a more complicated print by adding a logo that adds nothing to the function". So, while I am stilling giving credit where credit is due, I removed it because I didn't want it.

You may need to get a little creative with the supports or rotate it to make it work. For me, I printed it so the big side was on the bottom, line supports with build plate only so the supports built up from the larger holes. I did need to do a little clean up on the little overhang that you cant see though. I'm sure there is a better way but this worked good enough for me.

Design Notes:

Version 1: Does not take into consideration the flex tube support.

Version 2: I am still tweaking this design a little. The first version that didn't take that upper support into consideration works, but its not as secure as I would have liked it to be. This version should be an improvement on it. As of the time of writing this, V2 has not been tested yet.
