Kuro's Compact Geared Bowden Pushfit Extruder

prusaprinters

<p>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.</p> <h3> Instructions</h3> <p>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:</p> <ul> <li>2 springs for idler tension </li> <li>3 625zz bearings </li> <li>1 MK7 drive gear </li> <li>1 M5x40mm hex headed bolt </li> <li>1 M5x30mm bolt <strong>*2 M5 lock nuts (helps to avoid overtensioning the big gear axle)</strong> </li> <li>2 M3x35mm bolts </li> <li>1 M3x20mm bolt <strong>*1 M3 x 6mm cup point grub screw</strong> </li> <li>2 M3x10mm bolt <strong>*1 M5 or M6 BSPT pushfit for 4mm tubing</strong> </li> <li>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.</li> </ul> Category: 3D Printer Extruders
