Satyr 3 Open Headphone Grille - 11 Patterns, Lighter than Stock

Eleven new front grilles (fasciae) for the Satyr 3 DIY headphones. Instead of a plate full of holes, each one is a single open window or a few slim bars inside the stock outer ring, so more of the driver is free and the grille weighs less.

All eleven keep the stock interface 1:1: 92 mm outer diameter, 5 mm height, the same chamfered outer edge and the two blind mounting holes (4.4 mm, 4 mm deep) at the same positions. They swap straight in for the original part.

The eleven open grilles

Two families of four and three singles. Mass is for PETG (1.27 g/cm³). Open area is measured at the base, without the mounting holes. The stock grille is 14.79 cm³, 18.8 g and 43 % open.

• Eclipse - off-centre round window, a thin crescent on one side. 10.96 cm³, 13.9 g, 48 % open.

• Eclipse Bold - wider crescent. 11.70 cm³, 14.9 g, 44 % open.

• Eclipse Diagonal - crescent on the diagonal. 10.94 cm³, 13.9 g, 48 % open.

• Eclipse Stepped - two stepped crescents. 11.81 cm³, 15.0 g, 45 % open.

• Facet - hexagonal window with 45° bevels. 10.99 cm³, 14.0 g, 52 % open.

• Facet Pentagon - five sides, one corner sideways. 12.37 cm³, 15.7 g, 48 % open.

• Facet Octagon - eight sides, the lightest of the set. 9.59 cm³, 12.2 g, 57 % open.

• Facet Turned - hexagon turned 30°. 11.89 cm³, 15.1 g, 49 % open.

• Spoke - three slim spokes meeting off-centre, no hub. 9.76 cm³, 12.4 g, 57 % open.

• Sash - one offset bar across the window. 10.07 cm³, 12.8 g, 56 % open.

• Squircle Oblong - one rounded-rectangle window, the one on my own Satyr 3. 12.01 cm³, 15.3 g, 45 % open.

Every file is a single watertight solid, checked on the exported STL: outer diameter, height, hole depth and cap, no overhang steeper than 45° when printed base down, and at least 2 mm of wall around each hole.

Same mounting as the stock grille

The mounting interface was measured from the original fascia and rebuilt 1:1: 92 mm across, 5 mm tall, two blind holes on the Y axis, 38.8 mm either side of centre. Every window runs wide across the cup, so it clears the cup vents and the jack.

Lighter and more open

Each of the eleven weighs 16-35 % less than the stock grille and leaves more of the driver uncovered.

Printing the grilles

• Base (flat side with the holes) on the bed, no supports, no brim.

• Suggested settings: PETG or PETG-CF, 0.16 mm layers, 4 walls, 40 % gyroid infill. Carbon-fibre filament needs a hardened nozzle.

• About 40 minutes per grille on a Bambu Lab P1S (sliced estimate), 12.2-15.7 g.

• The 3MF is the sliced project I printed Squircle Oblong from (P1S, PETG-CF).
