Coffee Grinder Hand Crank Retainer (C-Clip)

I enjoy using my KINGrinder to manually grind my coffee beans for my morning cup of coffee, however shortly after I began using this particular manual coffee grinder, I discovered an apparent design flaw. An O-ring is used to keep the grinder lid secured to the crank handle, which nestles into a little recess on the hand crank shaft. The problem is, the O-ring rolls out of the recess quite easily and would either fall into the grinder or go flying across the room. I actually thought I had lost it, which prompted me to design this replacement, but the O-ring reappeared on the countertop about a week later. A secondary improvement to using this C-clip retainer over the O-ring is the crank handle no longer squeaks when rotated (although I solved this while still using the O-ring with a little olive oil applied to the O-ring and lid).

Print Recommendations:

• I used a 0.25mm nozzle at a 0.1mm layer height for better detail, although a standard 0.4mm nozzle at 0.1-0.2mm layer height should be fine.
• Default perimeter & infill settings, or whatever you prefer.
• I recommend blocking seams at the inner opening of the C-clip to ensure the clip fits around the hand crank shaft properly (see image below).

Happy grinding! Err… Printing?… Both! Let's go with both!
