Hexagon and Alu-Extruder Carriage for DaVinci

Just as the title says: You can now rid yourself of that awful, stock, hotend / extruder combo! I've created this part specifically for RepRapDiscount's Hexagon Hotend and Printrbot's Aluminum Extruder. Plus, with its unique "Clip-On" design, you no longer have to dismantle your entire printer to replace, maintain or modify your carriage.
It runs extremely cool - the heat sync is cool to the touch. I have now put approximately 12 hours on the carrier, 6 of which have been in PLA. I have tested up to 60mm/s with no issues, and more specifically no clogging.

Additional Note: For those willing to take a well worth it risk, here are all of the parts i bought:

• Hexagon Hotend Kit: http://www.reprapdiscount.com/hotends/67-hexagon-hotend-set.html
• Alu-Extruder: http://printrbot.com/shop/printrbot-alu-extruder-2/
• Bonus part: .3mm Nozzle: http://www.makerfarm.com/index.php/3mm-hexagon-nozzle-for-1-75mm-filament.html

Update:
Unfortunately, I have lost the original IPT for this part after transferring computers. Consequently, I can no longer make edits to it, so it is no longer a "work-in-progress". However, I will be working on a new carriage assembly in the weeks to come (sadly I have many studies that also demand my attention).
In the next built I plan to address some of the small "bugs" I have noticed in this one, so please check back! Any recommendations are welcome.
