Tevo Tornado - Flush Strain Relief

This is "flush" design for strain relief of heater wires on Tevo Tornado print-bed. Might seem less sturdy than other designs, but it does the job and looks much nicer.

M5 nut is recommend to fix it better from the bottom.

I use M5 nuts (with plastic washers!!!) on all bed-leveling bolts, so they don't rotate when I turn leveling knobs. Plastic washers are needed to avoid glass cracking by more even distribution of pressure when tightening the nuts,
