Ender 2 Heat Bed Cable Strain Relief

Strain Relief for Heated Bed Cable on Ender 2

Here is a plate to be mounted with washers and nuts under your heated bed.
I highly recommend insulating your bed and using the appropriate file.
I also recommend using the 3 screw version to hold planarity

I have made 4 versions:

ender_retain_3_insul.stl I recommend this file
ender_retain_3_no insul.stl Use this if you don't insulate bed

ender_retain_2_insul.stl Use this if you must print a smaller version- but prone to skewing
