Orange Peeler Challenge

Start simple: sketch cleanly, constrain smartly, and discover how symmetry saves your sanity. A tiny model that teaches big habits — and yes, it actually 3D‑prints brilliantly.

Hexagon Bracket

Hexagons, constraints, cut‑outs, and your first proper radial array. Build a bracket that looks tougher than it is — and learn how cosmetic threads make everything feel more ‘engineery’.

Vee-Block Challenge

Multiple bodies, shared sketches, and a model that becomes an assembly right in front of you. This is where CAD starts feeling like real engineering instead of just shapes.

Pencil Pot

A classic revolve: sketch a profile, spin it, shell it, pattern it. A perfect warm‑up — and another model you can actually print and use on your desk.

Light Shade

Two revolved profiles collide to make something surprisingly stylish. Learn how intersecting geometry can create forms you’d never sketch directly.

Wine Class

A tricky profile, a delicate shape, and the art of knowing when not to do everything in one go. Build a wine glass that looks elegant instead of… melted.

Lofted Pot

Lofting isn’t magic — it’s maths with attitude. Match every vertex, line them up properly, and watch the pot take shape instead of spiralling into a twisted disaster.

Transition Pipe

Circle meets square in the most dramatic loft of the course. Offset your planes, align your points, and make two totally different shapes blend like they were meant to be together.

Door Handle

Two profiles, two perpendicular planes, one curvy rail running the show. Guide the loft along the path and sculpt a handle that actually looks like something you’d grab.

Screw

Your first proper thread: a tiny profile, a precise pitch, and a helix that finally makes sense. Build a screw that looks like it could actually hold something together.

Propellor

A partial pitch and a fraction of a revolution — just enough twist to make a blade. Then spin it around the hub and suddenly you’ve built a propeller that means business.

G-Clamp

ACME threads: chunky, square‑shouldered, and deeply satisfying. Model the male and female halves so they mesh perfectly, then admire your clamp like a proud engineer.

Desk Tidy

A simple profile, a curvy path, and suddenly you’re sweeping geometry like a pro. Follow the arc, keep it centred, and watch a flat sketch turn into a tidy little organiser.

Whisk

One wire is clever. Six wires is engineering. Sweep a tiny profile along a looping path, then spin it around the hub to build a whisk that actually looks ready to beat something.

Coffee Cup

Revolve the mug, sweep the handle, fillet the joins — and boom, you’ve made the world’s most CAD‑approved coffee cup. Just don’t try to drink from the STEP…
