Yet another acoustic Amazon echo dot mount / stand / holder with cool floating style design!
Center cone reflect the sound from bottom facing speaker to 360° and improve sound quality.
Loooong circular bridging. If it is able,make sure to set the support upper clearance to 0 layer.
The original size model is "echodotmount_PLA.stl".
But I printed "echodotmount_PETG.stl" it have larger holder-ring to compensate PETG shrink.
I recommend to print with ~PLA.stl and scale XY (and Z) in slicer to compensate your material shrink.
