Side Release Buckle design guide/material?

You guys are a great resource. Thanks!

Anyone can comment on ABS vs. Delrin for the application? ABS I would guess in cheaper, not sure about other physical properties or transparency.

IAB, is Accura Clear Vue similar in physical properties to ABS/Acetal? If I don’t need the SLA transparent, is there another material you’d suggest?

Checking out slab stock now …
