Kuro's Compact Geared Bowden Pushfit Extruder
thingiverse
I modified Kuro's excellent MK7 based geared Bowden to use an M5 or M6 BSPT pushfit connector. The hex nut retainer channel is gone, replaced with a bolstered hole for the pushfit. Instructions BOM is the same as Kuro's, but replacing the 5/16" nut with the BSPT fitting. I've also added a couple of specialty things you might not have on hand: 2 springs for idler tension 3 625zz bearings 1 MK7 drive gear 1 M5x40mm hex headed bolt 1 M5x30mm bolt 2 M5 lock nuts (helps to avoid overtensioning the big gear axle) 2 M3x35mm bolts 1 M3x20mm bolt 1 M3 x 6mm cup point grub screw 2 M3x10mm bolt 1 M5 or M6 BSPT pushfit for 4mm tubing Assorted nuts and washers Follow Kuro's instructions outside of the tube attachment. To mount the pushfit, use an appropriate wrench to slowly self-tap with the pushfit connector.
