The following video is the early prototype:
This was a project of mine from a few years back, its pretty much a done deal, I dont own these printers anymore but when I did, this was the tool head I used.
If I can find the Step files I will upload, but it should be perfectly fine to use on any of the KP3S range.
Ket Points:
Please print from ABS or better, the one displayed in the images was printed from ABS-CF, its all been designed to print face down as per the attached image, and has built in supports where required (Blower inlet), so no need to add any.
This will require M3 heat inserts, and and various M3 bolts, and 4 x M2.5 for the hotend, I used Titanium bolts for the hotend and for mounting to the printer, and alloy bolts for everything else, this makes it super light but quite strong.
If I find the step files, I will post them up here and I will also list the exact leng bolts required.
The author marked this model as their own original creation.
