Sunhokey Prusa i3 Knob Customizer

thingiverse

I wanted a better knob than the stock metal one on my Sunhokey Prusa i3. By the time I wrote code to make what I wanted, I decided it'd be easy enough to expand it and make it a customizer. It should be relatively easy to modify for other printers/knobs to fit your uses, so I've provided the .scad file as well. If the knob fits too loosely, you'll want to decrease the inner spacing, as it is currently set at 7mm (the stock knob you're attaching to is 6mm). I'm still working on calibrating my printer (just built it last week) so I needed the extra room to make it fit properly. Feel free to ask questions - I'd be happy to add modifications for other printer/knob types if you can provide me with a picture and measurements of the knob you want to make it fit onto. Print Settings Printer Brand: RepRap Printer: Sunhokey Prusa i3 Supports: No Resolution: 0.1mm Infill: 100% Notes: In general, you shouldn't need supports. However, if you do the "pirate" nub type, and the handles of your 'helm' are not at the top of the knob, you will want to use supports. How I Designed This Designed in OpenSCAD, and the .scad file is provided so you can make whatever modifications you want (for example, to change the connection type to fit the knob on a different board). I've added a recommended settings text file that details out my recommended settings for each type of nub, so you can get a decent starting place when you make mods (it was originally comments in the code, but Thingiverse's Customizer thought the variables in the comments were actual variables and everything got messed up, so I moved them to a separate file.)
