Bondtech Extruder Remix for CR-10

thingiverse

Since I've always thought the stock extruder on my CR-10S was one of its weakest points, I purchased a cheap Bondtech clone for 20 bucks to see if it would improve things. However, I wasn't satisfied with this new setup due to the subpar bowden coupling and the tube constantly slipping out. I also didn't like that the Bondtech had to be mounted at a 90-degree angle on my CR-10S, which blocked the Z rod otherwise. What's more, I've never been a fan of the closed design of the Bontech to begin with. After disassembling my cheap clone, I was pleasantly surprised to find that the moving parts inside looked quite good. This led me to decide that I would try and build my own version using only the stock parts from the clone. In addition, I wanted to challenge myself by improving my Fusion 360 skills since I'm still a newbie. I wanted to see if I could actually create something useful with this software. I'm thrilled with how it turned out; so far, it's printed for ~20 hours and has given me excellent results. However, I don't know exactly how close to the real Bondtech my clone is or how many of them are out there, so I can't guarantee that it will work for every setup (mine is called "Redrex"). Also, I designed the parts to be a very tight fit; mine was printed at 0.12mm layer height and I assume the holes might be too tight if you use larger layer heights. Perhaps this will be useful for someone else.
