"Octa Digisol" is an updated version of the "Octa Digit", but then without the "nipples". This design is more streamlined for a high gloss and stainless steel...the Octa Digit is better for brass, gold plated steel, silver etc...but the geometry is the same in each. Available in all 3D printable sizes and materials upon request. More at:
