MPCNC Drag Chains Supports

This is set of drag chains supports for MPCNC project - https://www.thingiverse.com/thing:724999.
I used drag chain 10x10 from AliExpress: https://www.aliexpress.com/item/Transmission-Drag-Chains-3D-Printers-Parts-7-7mm-10-10-mm-Plastic-Towline-Part-1M-Cable/32813659240.html?spm=a2g0s.9042311.0.0.pvmvUB to manage cables. Bar supporting Z axis drag chain is made of PVC electrical duct cover 15mm wide. Z axis support holds electrical socket (diameter 44 mm) to connect spindle (Dremel in my case). This socket is controlled by relay switched by M3, M5 commands.
