What a ws2812 16-led ring diffuser is
A diffuser cap and base for a 16-LED WS2812 ring (44.5 mm outside, 31.7 mm inside). The base is a 50 mm disc with a 45 mm ring pocket and a 5 mm wire slot, and the cap is a 0.8 mm dome that snaps on. Print the base in black PLA and the cap in white or clear PETG so the pixels blend.
The 12-LED ring is 37 mm across and the 24-LED ring is 66 mm, so size the pocket to your ring. Open the ready-made model in SpeakCAD for free, change the diameters in the viewer or the chat, then download the STL.
