3D Viewer 3.0.0

3D Viewer 3.0.0 adds print checks to the viewer: wall thickness, overhangs, a mesh check, and weight and cost. Measuring and the cross-section get new tools too.

New

Wall thickness

Tools → Wall thickness colours the whole model by how thick its walls are.

• Red is below Thin below (0.8 mm by default). Thicker walls go orange, yellow, green and then blue.
• The thinnest spots are labelled on the model with their thickness.
• It runs in the background, with progress, on models of up to 6 million triangles.

Overhangs

Tools → Overhangs shows in red the faces that will need supports.

• The Angle slider is the slicer's overhang threshold, 45° by default.
• It says how much of the surface needs supports. Faces on the bed don't count.

Mesh check

Tools → Mesh check finds and highlights:

• open edges (holes), in orange;
• non-manifold edges, in purple;
• flipped faces, in red.

It counts each kind and the separate parts. A hollow inside a part is recognised as such, not as flipped.

Weight & cost

Tools → Weight & cost shows the volume, plastic used, weight, filament length and cost.

• Materials: PLA, PETG, ABS, ASA, TPU, Nylon, PC, PLA-CF and resin.
• Settings: infill, number of walls, and 1.75 or 2.85 mm filament.
• Prices: the admin sets the currency and the price per kg of each material in Admin → Print cost. Each person can change a price for themselves in the viewer.
• Accuracy: it is an estimate without slicing, usually within 10–15 % of a slicer, without supports.

Measure

• Distance now shows its ΔX, ΔY and ΔZ parts.
• Circle: click three points on the edge of a hole or a round part to get the radius, diameter and centre.
• Angle: click three points to get the angle at the middle one.

Cross-section

• Type the exact cut height, or the distance from the left side or front.
• The cut face is hatched. This can be turned off with Hatched cut faces.

Fixed

• The cross-section's red cut face could be hidden behind the model's own inside faces. It shows again.

Update

Pull the new image and redeploy (or docker compose pull && docker compose up -d), then hard-refresh your browser (Ctrl+Shift+R, or Cmd+Shift+R on a Mac).
