Quick Release Knob - Multiple thread types

Quick-release (quick-acting) knob that slides in and out of clamping position, ideal when the knob must be completely removed for loading. Tilt knob to slide in, then straighten to engage threads and tighten. To remove, loosen knob, then tilt to slide out.

I have not printed every version of this as I only have an M4 rod and a 5/16th rod to test with. Any issues or requests let me know and I'll see what I can do.

Changelog:

• v1.00
  • Initial release
• v1.10 
  • Adjusting slide hole angle from 12° to 15° 
  • Adjusting slide hole dimensional increase from static 2mm to 0.5mm which will create more of a snap when straightening to engage threads
  • Adding thread size as imprinted text onto model
  • Added more clearance for thread parameters to account better for 3D printing plastic expansion etc.
  • Added suggested print settings
     

Suggested Print Settings:

• Layer Height
  • Around M8 (5/16") or larger, 0.2mm will work. 
  • Anything smaller than that you'll want to go 0.15mm
• Perimeters
  • 2 for the smaller knobs
  • 3 for the larger knobs (larger knobs give more leverage and will suffer more)
• Infill
  • 15% grid for the smaller knobs
  • 20% grid for the larger knobs (larger knobs give more leverage and will suffer more)
• Material
  • PLA works just fine but is prone to snapping “under load” (impacts, flex/weight).
  • PETG works better for “under load” items as it has a bit of flex, but due to how PETG likes to sag a bit when it prints, you'll want to screw on and off a few times to better develop the threads
• Speed
  • I tend to print on the “fast” settings of my printer, but it's fairly dialed in. If your printer tends to not be dimensionally accurate, slower is of course better.
