Summary

A simple knob for the top of the 5/16" all-thread on the Printrbot Simple beta. Since the printer doesn't have endstops, it's nice to be able to make fine adjustments to the printhead height.

Please note that as with many of the things designed for the original Printrbot Simple beta, this knob is not usable with the current production Simple, which now comes with Acme rod; instead, try http://www.thingiverse.com/thing:145804

Instructions

This knob is generated by jridley's very nice OpenSCAD library for hex-head screw knobs: http://www.thingiverse.com/thing:11797 using these parameters:

screw_knob(26, 5, 20, 6, 3, 12, 0.4, 8.3, 13, 6);

I printed it (on the Printrbot Simple) with PLA, 3 perimeters, 40% infill. Clear the hole with a drill bit, knife or file, then press fit a 5/16" nut into the hex hollow. Thread a second nut onto the all-thread, and use it to lock the knob in place.

For anyone having problems slicing the knob, I've uploaded a gcode file based on the settings for our Simple. You can try printing as is and it ought to be fairly close, or you can tweak the start G-code to reflect your calibration numbers.You may also want to look at JohnSL's version here: http://www.thingiverse.com/thing:91438

Not sure if this was a typo or not but the threaded rod on the printrbot simple metal is 1/4 inch in the description it says 5/16ths was this different on the simple?

Not a typo - this is for the original Printbot Simple BETA, not the current production printer. The beta kit had ordinary hardware-store threaded rod, not an Acme screw. I don't have either of the current versions of the printer (Maker's kit or Metal) so I have no idea what size is being used today.

Thanks for getting back to me, i had been waiting to print until i knew for sure. The Simple metal (1403) uses the 1/4" acme threaded rod so Ill look for another or design my own. Thanks again.

I can't get this to slice right, could you get the gcode possibly?

Hmm, I can certainly slice it and send you the file, but it will have my settings, not yours. If our calibrations are the same that would be okay, if not your print won't come out. You might have to edit the gcode file to adjust.

I can edit the gcode to my settings, just need it for the print itself, is that possible?

I just uploaded the gcode file. . .

Thank you! Printed, but a little to small. Some layers got squished. I'll re-print it tomorrow!
