CNC Machined 6mm wooden supports.
This are the needed piece to adapt silicone ears to Dummy Heads or any enclosure needed in a binaural or recording system.
They seem like a stupid piece of wood, but after years of practice, I realiced how this crucial part of the kit made things extremely easy.
The ear canal hole is 8mm diameter. Drill holes are 5mm.
Material thickness is 6mm, other materials and thicknes can be achieved.
If you need any specific measurement let me know.
