Most tray customizers give you rectangles and circles. Here the cavity is the object's own footprint. The pocket below is a body with a tab on it — eight points carrying the four numbers you would read off a caliper: body length, body width, tab width, tab height — so dragging them on the sketch canvas turns it into YOUR part. Size the tray to your drawer, set the fit, print it flat.
Each parameter below rebuilds real geometry on every change — this is parametric CAD, not a scaled mesh.
| Parameter | Default | Range | What it does |
|---|---|---|---|
| Corner radius | 2 mm | 0 – 8 | Rounds every corner of the traced outline — a sharp-cornered part still gets a printable inside corner. |
| Fit clearance | 0.5 mm | 0.1 – 3 | Grown around the outline on every side; 0.25 snug, 0.5 drop-in, 1.0 loose. |
| Pocket depth | 7 mm | 1 – 40 | How deep the part sinks. Clamped so a 1.5 mm floor always remains. |
| Tray length X | 140 mm | 60 – 400 | Outer length — measure the drawer, not the part. |
| Tray width Y | 100 mm | 60 – 300 | Outer width of the tray. |
| Tray thickness | 10 mm | 3 – 60 | Must clear the pocket depth plus a 1.5 mm floor. |
That is the point, and it is eight points to drag. The outline is authored as literal coordinates, so you reshape it on the sketch canvas the way you would sketch on paper — add or move points for a notch, a step, a second tab — or hand the agent measurements (or a photo) and ask for a different silhouette outright. The tray, depth and fit stay on the sliders either way.
0.25 mm per side for a snug locating fit, 0.5 mm so the tool drops in one-handed, 1.0 mm if the tray will be handled with gloves. The clearance is added around the outline by the model, so the eight points stay the object's own measurements — loosening the fit never redraws the shape.
Yes. A pocket cut down from the top face leaves a flat floor and vertical walls — nothing overhangs. Print it flat on the bed in PLA or PETG at 0.2 mm layers, no supports and no brim. Keep the depth under about two thirds of the part's height, though, or your fingers cannot grip the part to lift it out.
