this is a 19" 1u cable manager for your rack

You need to glue the top of the cable manager(in the grooves that are printed) to the rest and than you can snap/slide the front in and out of place. it is designed to be glued as to not need support and still be printed in the best orientation for the “fingers” to be strong and not snap off.
 

no supports needed 
you can ignore the warning about floating regions if u get it 

if u have a large format printer (330x330) there is a large cover that covers a full u , in this case supports are needed 

you can also print something else from the collection and it will fit in the rack , they screw together whit 4 m4 screws and nuts :
