Parametric Pen & Marker Holder - Customizable

Boost Me If this little holder earned a spot on your desk, a quick boost helps the next colorist find it too. Cheers!

Tired of your square-bodied markers rattling around in round-hole holders like they don't belong? Yeah, we thought so. 🖍️

Introducing the marker holder built for the way markers are actually shaped. Whether you've got a stack of Ohuhus, a pile of Crayolas, or a mixed crew of brush pens and highlighters, this fully parametric holder uses rounded square slots to cradle each marker snugly — no wobble, no rotation, no awkward gaps around the body. Works just as well for round pens and pencils too if you want one holder to rule them all. 🎨

How it works ⚙️ Just plug in how many columns and rows you want, set your slot size and corner radius, and the tray builds itself around your numbers. The outer dimensions auto-calculate so everything fits perfectly with clean walls and even spacing every time. No math required on your end — that's what the parameters are for. The angled stand is fully parametric too — it automatically adjusts its dimensions to match whatever size tray you build, so the two always fit together perfectly right out of the slicer. 🖨️

A few ways people are using this 💡 Got a full set of Ohuhu or Copic markers taking over your desk? Set the slot size to 16mm, plug in your row and column count, and every marker drops in cap-up so you can see what color you're grabbing. 🎨

Running a craft table with Crayolas and washable markers in constant rotation? Set a slot size around 12mm, bump up the rows, and the whole rainbow stays visible and grabbable. Bonus: square slots mean no marker spinning the label out of view. 🌈

Want one holder for a chaotic mix of fine liners, Sharpies, brush pens, and highlighters? Set the slot size to fit your chunkiest pen, dial in a larger corner radius for a softer fit on round bodies, and everything lives together in one organized lineup. 🗂️

One heads up — the stand will appear laying on its side in the customizer preview. Don't worry, that's intentional. It's the correct print orientation for clean results with no supports needed. 👍
