rp3d Pangu i3 Extruder Mount for Chinese All Metal J-Head (e3d clone)

This is a modification of the standard direct drive J-Head extruder mount that comes with the uber cheap rp3d Pangu i3 from Aliexpress.

The J-Head that the original was designed for is considerably more expensive and not as common on Aliexpress than the cheap all-metal hot ends (e3d v5 clones I think?) also sold as J-Heads.

While the mounting collar is similar, it's a difference size and so the all metal extruder doesn't fit in the original mount, also I wasn't that enamoured with the two-loose-screws which secure the original J-Head into the mount.

This modification provides for a solid clip-in mount and has a secondary part to retain the extruder if necessary, on my print it's pretty tight press-fit, I suspect that the retention clip can be omitted entirely.

The retention holes are 3mm diameter, probably some M3 screws will self tap in there with the usual shrinkage if you do need to put it on.

Note that you will need to change your z stop, as the extruder is a bit longer.

Have tested it, works well, as suspected the retaining piece does not appear to be necessary for me, but your milage may vary (if your print isn't such a tight fit). Recommend fan on at 100% all the time if you don't have a fan on the extruder heatsink itself (recommended).
