This is a merged ground plate model from models
I have basically wanted to print Ender 3 S1 Pro Heated Bed Cable Chain from 2nd model, but I did not like the idea of gluing the bottom plate, so I decided to use ground plate approach from the 1st model. So this merged model came to existence. Thanks to original designers of both models.
The author remixed this model.
A totally new ground plate / bottom part for the heater bed cable chain by borrowing ideas from two genius designs.
