Customizable Angle Gauge Blocks - 1 to 60 Degree Wedge Presets, Native Playground Recipes

Customizable angle gauge blocks made with native TrueGeometry Playground commands. Each set has seven wedge plates with a flat reference bottom, a sloped top at the stated angle, square end walls and a raised number label. Change any angle by editing one variable line in the recipe.

IMPORTANT: Unprinted, uncalibrated plastic wedge blocks, NOT certified steel angle blocks. No block has been printed or checked with a protractor or sine bar. The CAD angles measure within 0.0001 degrees on the exported STL files, but a printed part will be far less accurate: printer calibration, plastic and elephant foot decide that, typically a fraction of a degree at best. Do not use these for certified inspection or safety-critical setups. All gallery pictures are CAD renders, not photos of printed parts.

TWO PRESETS

Machinist: 1 / 3 / 5 / 10 / 15 / 30 / 45 degrees (plate 145 x 62 mm).

Fabrication: 5 / 10 / 15 / 22.5 / 30 / 45 / 60 degrees (plate 142 x 74 mm).

Each block: 32 mm sloped face, 6 mm thick, flat bottom face. The stated angle is between the flat bottom and the sloped top. The only real corner that matches a number is the top right: 90 minus the stated angle. Small blocks are therefore poor corner gauges. Use them as wedges on a flat reference surface.

WHAT TO PRINT

The first STL is the upright machinist reference, named REFERENCE_DO_NOT_PRINT, so the finished model shows first. Print the two flat print plates (02 machinist, 03 fabrication), not the upright references (01 and 04). The blocks lie flat, so no supports are needed.

CUSTOMIZE IN TRUEGEOMETRY PLAYGROUND

Every recipe is variable-first: ANG1 to ANG7 (degrees), THICK, FACE, BASE_H, GAP and LABEL_SIZE sit at the top. Example from the attached custom recipe: change /set_var ANG2 3 to /set_var ANG2 2 and the second block becomes a 2 degree wedge. Also change its label line /sketch_text 3 to /sketch_text 2, because the raised number is plain text. We tested ANG2 3 to 2 together with THICK 6 to 8: the exported STL measured 2.0000 degrees and 8.0 mm with a clean mesh.

Rules: keep ANG1 to ANG7 ascending (the second row is placed from block 7) and stay between 0.5 and 75 degrees. The scripting has no trig, so sine and cosine are computed with a series written in plain arithmetic.

LABELS AND HANGING HOLE

The raised pixel numbers are small, with strokes of about 0.4 to 0.5 mm, which is borderline for a 0.4 mm nozzle. Some digits may come out rough. The labels are cosmetic, the angle lives in the plate outline. There is no hanging hole by default: the native hole command adds degenerate triangles. A one-line optional hole is in the recipe header.

HONEST NATIVE MESH DISCLOSURE

No Boolean union, Boolean cut, external CAD kernel or mesh repair was used. These are native Playground exports, unmodified.

Machinist flat plate: 2,672 triangles, 18 closed shells (7 plates and the label letters). Fabrication flat plate: 3,812 triangles, 22 closed shells. Both flat plates: 0 zero-area triangles, 0 boundary edges, 0 non-manifold edges.

Upright references: 84 triangles, 7 closed shells (plates only, no labels), also 0 defects. The plates in a file are separate shells that do not touch.

PRINT AND CHECK

Start with one block. Check the first layers, shrinkage and elephant foot, since the bottom edge is the reference. Measure with a protractor or a known angle before relying on a block, and reject any that rock on a flat surface.

COMMUNITY TESTING

If you test-print these, please post a Make with printer, material, layer settings and a photo of a block against a protractor or known angle. Honest measured results help others judge the set. Do not report the CAD angle as measured accuracy.
