The case of Barrelhand's forthcoming Monolith timepiece is the first I have seen that has been strategically fine-tuned to save on the material costs associated with 3D printing.

Reminiscent of the Linde Werdelin SpidoLite and more recent pieces from DeBethune, the hollowed-out lugs are an easy win. It is the arrangement of the material egress holes around the inside diameter of the case, to enable a hollowing out of the internal case structure, that caught my attention. Apparently, Barrelhand founder, Karel Bachand, was likewise pleased enough with this innovation to call it out directly in the marketing material, referring to the 3D-printable, scandium-aluminum-magnesium alloy that the case is composed of as being air-core insulated.
