Tools You Might Need:

Design Inspiration

Let your desk space and pen collection guide the cup's size and shape.

Think about these elements:

FeatureInspiration
ShapeHexagonal (6 facets), octagonal (8 facets), or triangular (3 facets)
Height4–6 inches (fits standard pens)
Width3–4 inches (holds a handful of pens)
FinishNatural walnut (rich) or painted (bold)

Two ways to approach this:

  1. Structured geometry – Equal angles, precise faceting (clean, modern)

  2. Asymmetrical geometry – Varying angles, organic faceting (unique, artistic)

Choose what fits your style and comfort level.


Step-by-Step Inspiration

1. Picture Your Pencil Cup

Imagine it on your desk. Will it hold your daily pens? Match a modern office theme? Be a gift for someone who loves clean design? Let its use guide the size.

2. Choose Your Shape

Geometric options:

  • Hexagonal (six sides) – classic, balanced

  • Octagonal (eight sides) – more facets, more modern

  • Triangular (three sides) – bold, dramatic

Hexagonal is a great starting point.

3. Cut the Facets

For a hexagonal cup:

  • Cut six identical rectangles

  • Each edge needs a 30° angle

  • All pieces should be the same width

Height:

  • 4–6 inches (tall enough for pens)

Width:

  • 3–4 inches across (wide enough for a handful)

4. Assemble the Cup

Assembly method:

  • Apply glue to the angled edges

  • Clamp the pieces together

  • The angles should form a perfect circle

Use rubber bands or band clamps for even pressure.

5. Create the Bottom

  • Cut a hexagon (or your chosen shape) for the bottom

  • Attach with glue

  • The bottom should fit snugly

Test fit before gluing—adjust if needed.

6. Add Details (Optional)

Modern touches:

  • A slight flare at the top (wider opening)

  • A chamfer on the bottom edge

  • A subtle line engraved or burned around the middle

Details make it feel intentional.

7. Sand and Finish

Sanding progression:

  • 120 grit (remove tool marks)

  • 220 grit

  • 400 grit (for a silky finish)

Finish options:

  • Danish oil (warm, matte)

  • Beeswax (soft glow)

  • Matte polyurethane (durable)

  • No finish (the wood will darken naturally)

Pay special attention to the inside—pens will touch it.

8. Place on Your Desk

Add your pens, pencils, and markers. Step back. Admire the geometry.

Pro-Tips to Keep in Mind

  • Precision angles – Use a miter saw for accurate cuts

  • Even pressure – Band clamps work best for faceted assemblies

  • Smooth interior – Pens will touch the inside; sand it smooth

  • Stable bottom – The cup should not wobble

  • Wood expansion – Consider seasonal movement


A Few Thoughts Before You Start

A geometric pencil cup is a small project with a big visual impact. The facets catch light, creating shadows and interest throughout the day. Walnut's rich brown tones warm up any desk. It's a piece that looks like it belongs in a design magazine—but you made it with your own hands.
