Bobbin Lace Horseshoe

Summary:

For Bobbin Lace to prevent threads from rubbing against pins and pin holes while working.

How I Designed This
Design with a Slicer
Used PRUSA slicer in 2 steps. I have included the 2 project files and the STL for both steps.
You want to use the final step to print.

• Step 1a - Add cylinder
• Step 1b - Add negative cylinder offset from main circle.
• Step 2a - Add rounded corners (cylinders)
• Step 2b - added pin holes (negative cylinders)

Printing:

I print 2 at a time. No supports
