A made-up invention, drawn start to finish by the same pipeline you’ll use: the drafted parts list, three sketch options, the numbered sketch, a 3D concept model and the figure sheet.
A small lantern that hangs from the loop at the top of a tent and throws soft, even light across the whole ceiling. A fold-flat clip on top snaps onto the loop with one hand, and a dial around the middle sets the brightness. The base twists off to reach the rechargeable battery sealed inside.
Before anything is drawn, two AI tools tighten the brief. Check my brief reads every part together and flags anything a drawer would have to guess, each with a ready fix. Refine rewrites one part: add sizes, a more precise shape, a check against the sketch, or your own instruction. You see it before and after, then keep it or discard it.
Spring-gate carabiner on a hinge at the top. It hooks onto the tent's ceiling loop and folds flat for packing.
In your own brief: 3 free refines per idea, then as many as you need once you have the 2D Sketch. Checking the brief doesn’t use a refine.



Each option is checked against the brief, part by part. Pick the closest one, or redo it up to twice with a note.

Each part is its own solid. Turn it, see inside to find the battery pack (03), or spread the parts apart. Download it as STL for printing, or OBJ and GLB for viewers and Blender.

Made from the 3D model: the same shape and parts, with real materials and studio light. Use it in a pitch deck, a listing or a slide. It’s an artist’s impression, so treat the materials and colours as suggestions.


Concept drawings and a concept model, not formal patent drawings or an engineering file.
2D Sketch $5.99, or the full Design Set for $39.99. One time. Free to draft the parts list first.
