Basics
- OSE's Fork of CircularKnitic
Goals
Needle Accomidation
- Long tails
- Bent back tails
- Test 3D printed needles
Fabric Spool
- Apply constant tension on fabric
- Roll onto spool for easy handling and storage
Part Code
CKvars.scad
- need to define nominal distance between top of needle to top of CKp4.

CKp3.scad
- Added holes in base for long tails
- does this need to be bigger to allow for some slop?
- need to tweak CKvars.scad to make p3wall thicker
- need to optimize groove height to go as low as possible
- what to do if needle has bent back tail?
