Stained Glass Angle Jigs

Each facet is a bed for one piece of glass, so facets = petals. Six is a six-petal flower; two adjacent facets of a four is a butterfly’s wings; eight is a rosette. Size is measured across corners — 90, 120 or 150 mm, or 3½, 4¾ or 6 in. The usable bed is — per petal, because a triangle gives away a lot more of its width to its own corners than an octagon does. Units change the size ladder and nothing else — what is engraved on a jig is an angle, and 30° is 30° either way.

The number on a jig is the angle the glass actually sits at — the slope of the facet, which is what a protractor laid along a petal reads. You get 7 jigs plus the post, head and knob that bolt them together. The round numbers and the in-betweens split the full set exactly, so buying one of each completes it with nothing repeated.

Your printer does not change the jigs — every one is a single piece at every size. What it can change is the post, which prints standing up, so a tall kit needs the build height to match. If it does not, the kit is built as two stacks with a post each rather than being refused — split by alternate angles, so neither stack is all-shallow or all-steep and both are half the height. You get one more post, head and knob; every jig is unchanged.

There is no case, because the set is its own case. A post runs through the middle of every jig, a keyed head screws in underneath and a knob clamps the stack down on top — assembled is how it lives on the shelf and how it comes out of the box.

The stack alternates between the odd and even jig colors, top jig first, so a bolted set reads as seven jigs rather than one tall block.

The angle is engraved 0.8 mm into two faces of every jig and filled with the other jig color — a black jig gets white numerals, the white jig above it black ones. That is real contrast on every jig for no extra filament. On a single-filament printer the pockets are cut just the same and no inlays are shipped, so the numbers read as cut lettering rather than as nothing at all.
