Maker Select/Wanhao magnetic USB cord lock

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2344017.

This is a little device I cooked up to hold a USB cord against the control box so I don't lose connection in the middle of a print as has happened to me before. It uses this cord: https://www.amazon.com/gp/product/B00L9UGACW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and two disk magnets 3/4" x 1/8".

EDIT: Magnets are more like this: https://www.kjmagnetics.com/proddetail.asp?prod=DB2 Also added a STEP file for editing magnet sizes.
