Natural Inspiration
The earthy browns and gray
tones appear to draw from organic
materials. This choice could
be interpreted as an appeal to
authenticity and craftsmanship,
qualities that resonate well with
coffee enthusiasts who value
the artisanal aspect of coffee
preparation.
High-End Appeal
The chosen colors align with the
established identity of 1Zpresso,
reinforcing brand recognition
among existing customers. This
consistency helps create a unified
product line that customers can
identify as high-end and specialized
for coffee enthusiasts. By using
subdued and earthy colors instead
of bright, vibrant tones, the palette
communicates refinement.

CNC Turning
In analyzing the custom parts for the ZP6, it appears
that all parts are manufactured through CNC turning.
1Zpresso’s use of high quality materials such as the
6061T6 aluminum, and the necessity for precision
in each part, demand precision
manufacturing processes like CNC turning.
Medium Blasting
Each aluminum part of the ZP6 is finished with
medium blasting. The combination of this surface
finish with the hardness of the T6 tempered
aluminum allows the grinder to be handled and
used without scratches or dings from normal use
becoming prominent on the surface.
Leather Stamping
The leather grip of the ZP6 plays a prominent
role in the branding of the grinder. A texture is roll
printed onto the surface of the entire piece of leather
to provide greater grip during use. On top of the
texture, the 1Zpresso logo and name are prominently
stamped to reinforce the connection to the brand.
Technical Drawings &
Model Details
All parts of this model are drawn
within 200 microns of the original.
Threads, including the custom ACME
threads used in the adjustment
system, are physically modeled in.
Non-custom/standard hardware
models, other than the ball detent
pins, were taken from McMaster
Carr’s database of 3D models.
Some sub-assemblies were
unable to be disassembled due to
components having press-fit joints.
For example, the outer burr assembly
consists of three parts: the upper
housing, the lower housing, and the
burrs. The housings, press fit together,
were unable to be disassembled.
Parts unable to be disassembled
were modeled as accurately as
possible.
