Flying Extruder for Kossel Mini (Deltas)

SummaryFlying Extruder kit for the Kossel Mini. Can be used with any delta as well. See video below to see it in action. I would like to give credit to WASProject of Italy for their Suspended Bowden from which I derived the design for this Flying Extruder. http://www.wasproject.it/w/bowden-sospeso-di-wasproject/ The STL file included is for extruder drive gear with 6mm effective ID and 8mm OD (gear_radius=0) . Please change this value in the SCAD file if you have an MK8 drive gear (if 11mm OD, add 1.5 to gear_radius, i.e. (11-8)/2 ). DO NOT print plug.stl It is used for the SCAD file, for "tapping" a 1/8 BSPT thread SCAD files are included for your customization. (Nema 17.scad file is from Johann's Kossel Mini files) You'll need: M3 x 16mm screws for the nipples M3 x 35mm screw for knob M3 flat washer to insert in slot at back of extruder body M3 nut to insert at bottom of back of extruder body (to mate with knob) M3 x 24mm x 3 screws for mounting motor M3 x 12mm x 2 or similar course thread screws to fix plate to body Clear epoxy to glue fitting to body, as well as fixing the tightening screw to the knob. Bearing 16x8x5 for idler Bolt M5 x 16mm for idler hub (A simple 5mm dia x 20mm rod will also do. I used a 5mm rivet) 3/16" ID x 100mm x 3 Rubber Hose for suspending the plate to the nipplesPrint SettingsPrinter: Kossel MiniRafts: NoSupports: NoResolution: .2Infill: 30Notes: Use solid infill for fitting. 3 perimeters Post-PrintingGlue fitting to extruder bodyInsert the fitting into the extruder body front. Parts may need some filing to fit properly. Remove fitting from body and apply some epoxy to both mating sides. Re-insert the fitting to the body. Align the filament passage holes properly before the glue sets. I used a 2mm drill bit to make sure the holes are aligned.Custom Section
