VITRAL - Stained Glass Christmas Tree Lamp

A little church window for the shelf or the Christmas table. The front of the lamp is built like real stained glass: black lead lines frame more than 60 coloured panes, with a Christmas tree under a glowing star, red, yellow and blue ornaments, gifts in the snow and a blue sky full of snowflakes. A white diffuser behind the window spreads the light of an LED tealight, so every pane glows. Your name sits underneath on a black plaque in yellow glass letters, between two holly sprigs. Highlights - Built like real stained glass: Full-thickness 1 mm black lead lines and 0.8 mm coloured glass panes on the front face. No paint, no gluing.

- Your name on a glowing plaque: Open VITRAL.scad in OpenSCAD (or use the MakerWorld customizer), type any name and pick one of 5 fonts. Long names shrink to fit between the holly sprigs.

- 6 colours or all white: A ready 6-colour project (2 AMS) and a one-spool white version where the glass glows through thin layers and the lead stays dark.

- Even glow: A white diffuser panel right behind the window lights every pane, not just the middle.

- Slides together, no glue: The same rail box as BLOCK LAMP and AURORA: side walls with rails, the lid locks everything. About 5 minutes to assemble.

- No supports: Every part prints flat. The stained-glass front prints face down for a smooth, glossy front.

What you need - PLA in white, black, red, green, yellow and blue for the 6-colour version (about 174 g, mostly white). Six filament slots are needed for the window plate (two AMS units). Or about 165 g of white PLA for the white version.

- One 1.5" (38 mm) LED tealight in COOL WHITE. A model with a remote is recommended, because the tealight sits inside the lamp.

- LED tealights only. Never use a real flame.

Customizer - Name: Any name, up to about 10 letters. Long names are scaled down to fit the plaque.

- Font: Rounded (Fredoka), Script (Pacifico), Retro script (Lobster), Festive (Mountains of Christmas), Clean (Poppins). Install the fonts from VITRAL_fonts.zip first.

- Version: 6 colours (yellow glass letters) or all white (the name glows through a thin layer).

- Part: Export the stained-glass front with your name, the diffuser, or any other plate.

- Tealight cup: 38 to 44 mm. The default 40.8 mm fits standard 38-39 mm LED tealights.

Assembly - Switch the tealight on and drop it into the cup at the back of the base.

- Press both side walls into the long slots of the base, rails facing inwards.

- Slide the rear panel into the last rail and the diffuser into the 2nd rail from the front (flat side forward, arch pointing up).

- Slide the stained-glass front into the 1st rail, smooth side out. The two middle rails stay empty.

- Press the lid on with the star vents over the tealight.

Tips - Use a cool-white LED tealight: it keeps the blue and green bright.

- Keep the front face down on the plate: the glass is the first 4 layers.

- Turn off elephant-foot compensation or keep it small. The rails have 0.15 mm clearance per side.

- A panel feels tight? Two strokes of 400-grit sandpaper on its side edges.
