It's time I was wondering about to design a fast extruder change, to use any combination of nozzle, threaded tube full metal or with teflon tube. You can pre-assembly ready to use blocks you can mount with a couple of screws. I suggest you to mount assemblies touching bed with nozzle, so will be easy to find same zero Z when you reassembly that hotend on carriage mount. It has a couple of MPX connectors, to help a fast hotend change without hassles, only four screws. I suggest to glue both connectors in place, after checked if there is a good insertion. female connector has to be inserted in carriage holes. there is a blocker for the E3Dv6 or clone hotend, with an integrated 40mm fan support. I designed also a couple of fans, left and right version, with a new integrated blower, to print in four parts and glue together, without supports, only a good bridging work from yr printer. Isn't mandatory to mount two fans, is your choice, at left or right side. There are some brass inserts to fuse in, and to almost avoid this thing that's may be tricky, I added a nut version for E3Dv6 support, also if at least two M3x3mm insert need to be used in carriage mount, 'cause there's no room to accomodate a nut on top, to hang both fans. If someone has some tricks to solve it, please put in comments, thanks! I designed some little bumps on fan body as a glueing guide, that you can cut off easily after use with a cutter. There is also a reliable cable strain relief, for cables, with a zip tie holes to accomodate all. it's a WIP guys, I'm printing and testing all pieces to check reliability ! All thoughts, issues you discover, and suggestions are welcome, especially if not clear about assembly ! If someone need 123DX files to modify, feel free to ask me. Thanks in advance, hope you enjoy...=)
