The model is designed to install vertically onto the Skadis board, secured with two Universal Skadis Hook made by CSD_Salzburg (https://www.thingiverse.com/thing:2853257/files) here.
As per Gridfinity standard, 6x2mm magnets are required on the base plate and all the cable holder units. You may need loads of them i.e. 4 x 5 for the base, and 4 for each Gridfinity unit (although 4 magnets can be tard bit overkill for the purpose since most cables are light anyway). [note: 6x3mm magnets should work too]
Currently available in 1x5 grid, can stack on top of each unit (tested up to two stacks, and maybe use lesser magnets on the outer units to prevent pulling out the unit behind too).

Pending improvements:
-Make the side divots deeper for easier grabbing [V1.1]
-Narrow the opening to make for better cable retention
-Add more options for different number of units
