Design Purpose

This structure serves as an example for industrial product design, showcasing aesthetic CNC machining techniques, corporate promotional gifts, and surface finish analysis.

Deep Hole Drilling

Represents how the 6 deep chambers holding the pens are machined with flawless smoothness on a single axis without drill wander.

External Fluting

Demonstrates how the milled grooves (flutes) on the outer surface, originally meant to reduce weight and inertia on a real revolver, create an aesthetic grip feel in this design.

Indexing Notches

Highlights how the asymmetrical notches at the bottom, which lock a real cylinder in alignment with the barrel, add an industrial realism to the design.

Critical TolerancesVisual perfection and chamfer symmetry

A heavy and stable desktop organizer shaped from a single solid metal billet on CNC lathe and milling machines.

Engineering Note

In aesthetic parts like this, surface finish takes precedence over pure mechanical functionality. Reaming is applied to ensure no tool marks are left inside the chambers where the pens sit. To achieve flawless reflections on the outer surface, it goes through special polishing and anodizing steps after CNC milling.
