The file 'Sonic Pad USB Dual Stabilizer 3D Printer Model' is (stl) file type, size is 6.4KB.
This is a remix of https://www.printables.com/model/599440-sonic-pad-usb-stabilizer.
I remixed it to stabilize both the USB ports rather than only one. There are files for use with a serial cable, usb cable, or both.
