TNS's E3D V6 Carriage - Adjustable Edition

thingiverse

The purpose of this remix is to boost the smoothness of X axis movements for TNS's E3D v6 Carriage. The parts are designed to accommodate a variety of X rod distances and still provide smooth movements. This project began when I noticed that after installing my new igus bearing holders, it required more force to move. After investigating further, I discovered that my X rod distance was measured at 45.75mm while the carriage was designed for rod spacings of 45.95mm. This small difference caused a significant amount of force required to move. My goal was to design the carriage in such a way to allow different rod spacing to be used. An example is Leo_N's X axis parts, which will have issues as the center rod to rod distance is only 45mm instead of 45.95mm. This remix solves that problem. If you're not using an Anet and are using a Prusa i3 clone, this should work as long as the center rod to rod distance is between 44mm and 47mm. These parts were created from scratch in Fusion 360. I didn't have OpenScad, so I had to use the original STLs for dimensional references. TNS's original parts can be found here: https://www.thingiverse.com/thing:2099577 Features added: * Allows for center rod to rod spacings of 44-47mm to be used * Different version for 4 bearing printers * Adjustable fan height feature to allow for more fans or to adjust fan to perfect height * Fixes some dimensions on the original model * Not printer specific, can be used on other printer models * Interchangeable with Caps for TNS's parts * Fusion 360 files provided Changes: 4/24/2018 - 4 Bearing .STL version taken down for now. I need to design a belt holder for this version. Once I create or find a solution, I will post it up. 5/2/18 - Added the 4 Bearing Holder with its Belt holder bearing block. I integrated both components together to solve the issue. I also updated the STL and removed the old belt holder holes. They are no longer needed for this setup. This update only affects the 4 bearing version. 9/9/2018 - Updated the holder. Decreased the size of the holder so that it clamps onto the E3D stronger. 9/19/2018 - Updated the fan holder. Creating a new blower has caused me to notice issues with the old placement of holes, which creates the fan to be lopsided. 12/20/2018 - Clipped the corners of the 3 bearing holder to make room for the fan. Special Assembly Instructions: Most assembly instructions can be found here: https://www.thingiverse.com/thing:2099577. One special instruction is when attaching your bearing blocks to the carriage, you want the screws on the bottom bearings to be loose until you're ready to add the electronics. Tighten the top bearing screws first and then slowly start screwing in the bottom bearing screws. Parts I Used: I'm using Simhopp's belt holder. It works great with 16T pulleys on your printer. If you want to use this carriage with 20T pulleys, let me know and I can create something for you. I'm using Leo's Mistral Fan Duct. I like it but now that the height is adjustable, I may try out different fan ducts. I'm using these bearing holders. They fit perfectly and are easy to install. Suggestions: Feel free to comment or message me with any questions or suggestions. I'm always looking for feedback.
