Speaker cover / protective grille for 8cm (3.3") speakers

thingiverse

I designed this speaker protective grille / cover to fit Visaton F 8 SC speakers perfectly. It will also fit FR 8 and similar speakers with an 8cm diameter (3.3 inches). Measurements are very close to those of Visaton 8 ES speaker covers, which I didn't want to buy (6 euros for the part, 6 euros shipping costs, ...). Inner diameter and hole placement is based on original F 8 SC measurements (technical datasheet by Visaton). This grille / cover may fit other 8cm speaker chassis as well, as long as the speaker has flat mounting plates like the FR 8, F 8 SC, and similar speakers do. I wanted a robust-looking grill with a hexagon-mesh because this speaker is used in my workshop. The original grille by Visaton allows only mounting with flathead-screws, which I don't prefer. So this design has countersink holes to use 3.9mm, 3.3mm, or even 4.2mm countersink screws. Remember it's a 3D print! Don't get too much force on the screws!
