**UPDATE 3/15/2018**
Rossano95 shared his modified retainer. I removed the non-working and replaced it with his. Give Rossano95 a shout out if you use it!

**UPDATE 3/14/2018**
Rossano95 tested the 18mm mount version and it worked! The retainer didn't fit very well so he redesigned it. He may post as a remix or if he sends it to me I'll post it here.
**UPDATE 3/11/2018**
I added a untested hotend mount for a 18mm sensor. I don't plan on ever using it, so print it at your own risk.
**UPDATE 1/6/2018**
The blasted 2mm glass worked great...for a while. Unfortunately the last print stuck too good to the blasted glass and some glass came off when I pulled the part off. So I'm I went back to the hardware store and picked up another piece of glass. Adhesion is just fine with Ammonia cleaned class (Windex or any off brand window cleaner), but not as good as the blasted glass.
**UPDATE 12/30**
I decided to print the STL and it turned out great. I put in 4 brass inserts and then mounted the whole thing from the back in the lower position via the brass inserts instead of the lower mounting holes. I also bead blasted the glass which seems to help with adhesion. Please note that the duct is adjustable via the oval mounting holes. I had to mount it in the all the way up position to give it clearance between the nozzle and the bed.
---------------------------------
My CTC hotend broke and I was without a 3D printer. Luckily, I am in the process of building a HEVO and therefore I had the mount, hotend, extruder, retainer and duct already on hand. By drilling two extra holes and removing a little plastic near the X endstop flag in the mount, I made it fit the CTC carriage perfectly. Again, since my printer was down, I didn't design this in CAD and just modified the piece I had by hand and then created the STL for thingiverse so no guarantees that it will fit. I left a bridge in there for support that you will have to break out and I put in two mounting options; one way the way I mounted it by drilling holes, and another for mounting it with M3 brass fittings to lower the mount closer to the bed. The HEVO mount has the proximity probe spot already, so I figured I should add that sensor as well.
