Project Overview & Aesthetic Design
A geometric prism-shaped desktop organizer featuring an angled front groove for phone docking, rear slots for cable storage, and a side pillar for headphone resting.
Step-by-Step DIY Execution Guide
-
Cut three matching triangular panels from 1/4-inch heavy cardboard to form an equilateral triangular prism.
-
Cut internal divider baffles to create an enclosed hollow core.
-
Cut a 0.5-inch deep angled shelf slot into the front face to support a smartphone.
-
Drill two 0.5-inch holes in the top ridge to route phone charging cables cleanly through the hollow interior base.
-
Coat the exterior in textured limewash plaster paint for a modern concrete/stone desk aesthetic.

Pro Crafter Tip
Add a plastic bag filled with clean sand or aquarium gravel inside the hollow base before closing it to give the stand stable, non-tipping ballast.
