Modified Rotating Nozzle Platform

thingiverse

I was truly impressed by edlep's inventive design, but unfortunately, it wouldn't function properly with the hotends I use. This remix incorporates a few enhancements to his original design while streamlining it from four to three positions. A couple of additional features have been added to ensure more positive retention of the bearing through screws. The internal opening can now be stretched to accommodate space for pneumatic fittings. Moreover, the hotend mounting system has been modified (designed specifically for typical J-head dimensions). Additional mounting holes are also included for use with a classic rosstock/kossel platform. Further, mount holes have been added for a different motor that I am experimenting with. Instructions: To assemble this remix, print it at 0.1mm layers with 50% infill. The easiest way to do this is by placing the pneumatic fitting on a piece of tubing, loosely inserting the hotend into the mount, and spinning the hotend to initiate thread creation. Then tighten down the fitting using whatever tool can reach. Next, secure the retaining piece tightly. Finally, feed the leads up through adjacent holes. To use the SCAD files, you will need to download edlep's original STL files, edit the path, and proceed accordingly. In addition to printed parts, I used: 8 pieces of 3-meter-long 12mm screws, 2 pieces of 3-meter-long 10mm screws, 3 pieces of 3-meter-long 5mm screws, 6 pieces of 3-meter-long nuts, 7 washers for 3-meter screws.
