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
ender_retain_2_no insul.stl Use this if you must print smaller version and no insulation
I recommend printing in PETG or PLA Plus or other higher temp plastics.
it is stronger if printed with the main body flat on bed and few supports.
It gets attached to the bed's 3 screws, lock down with washers and nuts.
and I have made it to fit over bed insulation.
Use a cable tie over the connector block on the heat bed - most important, add others to secure cable.
If you haven't already, you can insulate your heat bed and increase its performance with these easy steps:
2 Foam insulation tape:
1 Cut and stick the foam to the underside of your heat bed, leave it about 1/8" away from edges,
cut holes for screws, do not cover soldered ends of heat bed connector.
2 cover entire bottom with metal foil to seal in heat. Let foil wrap around sides of heated and burnish down with your fingernail then trim.
do not cover or touch the soldered connector**
1 Now mount your cable protector cover over the 3 screws and add a nut to each screw and tighten in place
2 Now assemble cables and add zip ties in two places to secure cables, and mount to your machine!
Please note: I am constantly improving the files.
I am now printing each of these new improvements and until I have printed, tested and mounted each, I am going to leave the label work in progress.
I have tested the two versions with insulation. I cannot test others if anyone else wants to give feedback.
If you make one please photograph and post it to this page!!!
