Design a 3D-printable desk caddy from scratch

Your first real model in twyk: a desk caddy with a hexagonal pen cup, a phone stand with a cable hole and a slot for cards, ready to print. Along the way this tutorial teaches the editor properly, from moving the view to sizing things exactly and exporting for your slicer.

What you will make

  • A hexagonal pen cup
  • A phone stand with a cable hole
  • A slot for cards

Step by step

  1. The editor

    Find your way round: the shape library on the left, the plate in the middle and the properties panel on the right, where every setting of the selected shape lives.

  2. Moving the view

    Move around the model so you can check every side before you commit to a change.

  3. Plate and snap grid

    The plate is your print bed and the snap grid keeps everything lined up. Snapping runs from 0.1 mm to 10 mm, so you can work coarse or fine.

  4. The first shape

    Drop the first shape onto the plate. Every shape you add keeps settings you can change later.

  5. Moving, resizing, turning

    Drag, nudge and use the Move, Rotate and Resize switches, or type exact sizes in the properties panel. Naming parts keeps a bigger model easy to follow.

  6. Sides and bevel

    Change the number of sides on a round shape to get the hexagon for the pen cup, and add a bevel to soften the edges.

  7. Duplicate and Align

    Copy a shape, then use Align to line copies up exactly, instead of nudging by eye.

  8. Holes, Group and Merge

    Switch a shape to a hole to cut the cable gap and the card slot. Group keeps parts together; Merge fuses them into one solid.

  9. The ruler

    Measure sizes, gaps and margins on the model itself, so the phone and the cards actually fit.

  10. Ready to print

    Export a 3MF or STL for your slicer. Files are always in millimetres.

Frequently asked questions

Do I need any 3D modelling experience?

No. This is the first video in the series and starts from an empty plate. If you have used Tinkercad you will feel at home, because twyk also builds from solid shapes and holes.

How long does the desk caddy take to make?

The video runs about six and a half minutes. Most people pause and follow along, so allow longer for a first build.

What is the difference between Group and Merge?

Group keeps parts together so you can move them as one, while Merge fuses them into a single solid. The video shows when to use each.

Which file should I export for printing?

Export a 3MF if you want separate, named, coloured parts, or an STL for any slicer. Both are in millimetres.
