This model is a flush mount cutout template for the Tectonic BMR TEBM46C20N-4B Balanced Mode Radiator speaker driver. It may be useful if you are interested in designing a speaker using this driver.
The cutout depth in the STL exactly matches the thickness of the plastic frame of the driver; you will need to add additional depth to account for the thickness of the gasket in your speaker.
Screw holes are oversized and may require shrinking to create an airtight seal with your fastener.
The test print was made on a Prusa Mini+ using Overture PETG with 0.4mm nozzle and 0.2mm layer thickness.
The author marked this model as their own original creation.
