• spool outer diameter
• spool inner diameter
• spool width
• spool wall thickness
• clearance (small space to fit the storage)
• storage case wall thickness ( If you want thicker wall) These parameters are editable from the following link: https://cad.onshape.com/documents/c49a39f6a0f595d65edaa982/w/cf6d73b4fa8bfb4628929d2d/e/3ce0faf37f68245911e2e0c7
