8-Bit Pixel Yoshi Egg Lamp - multicolour without AMS, Bambu LED Kit 001, no supports

Yoshi's spotted egg in 14 x 16 pixels, lit from behind: the white and green pixels glow and the black grid stays dark. It is built around the Bambu Lab LED Kit 001, and every green spot is its own part.

4 colours (black, dark grey, green, white) without an AMS. Every colour is its own flat part: a black grid sits on a white panel and each colour drops into its window, so the light from behind shines through the colours. One filament per plate, no colour changes, no supports.

Lit by the Bambu Lab LED Kit 001 - not included, you have to buy it. The LED disc screws into a collar on the back: a threaded ring holds it by the edge, no glue or tape. The USB plug and switch go out through a covered opening under it. The white front panel spreads the light 19.3 mm in front of the LED, and the front comes off: 4 pairs of magnets hold it.

You will also need: a Bambu Lab LED Kit 001, 8 round magnets of 6 x 1 mm and a USB power adapter for its cable. It stands on its own flat bottom; the cable leaves from the back.

Checked before export. All meshes are closed and slice without repair, and the parts were checked for collisions in their assembled position, LED ring and USB cover included: 0 mm3 of overlap. A 3.5 mm cable drops into the notch and through the cover slot with 0 mm3 of overlap, and there is no black in front of any colour.

Plus a 3MF per colour plate, a small fit test and a colour map. Also a light test to pick the colour thickness (0.6, 1.0 and 1.4 mm).

Printing

PLA, 0.2 mm layers, 15 % infill, 4 perimeters. Every part prints flat, face down, no supports. No brim needed. About 15 h 29 min and 163 g in total. The files are already oriented - do not rotate them.

Print the fit test first: three inserts at 0.17, 0.25 and 0.33 mm. The model uses 0.25. If another one fits your printer better, ask and I will send that version.

Then the light test: each colour at 0.6, 1.0 and 1.4 mm on a white panel. Hold it 19.3 mm in front of the lit LED; the model uses 1.0 mm. If another thickness looks better with your filament, ask and I will send that version.

Assembly

1. Glue the black grid onto the white panel - its 3 pins fit the holes in the panel, so it only goes one way.

2. Put each colour into its window, resting on the white; the shape tells you where. Glue only at the edges, never in the middle of a colour.

3. Glue the 8 magnets into the body and the panel - check the polarity twice.

4. Fit the LED disc in the collar at the back, the cable into its open notch, and screw the ring in by hand. It takes discs 7.3 to 10.3 mm thick.

5. Pass the USB plug and switch out through the 24 x 16 mm opening and press the cover in, with the cable in its 4 mm slot.

6. Put the front on.

Size

132.5 x 150 x 30 mm.

Note: PrusaSlicer warns about loose extrusions on the black grid (03_Black_grid): a few thin joints between the green and the white start in mid-air. Print that part slowly and watch its first layers.
