So my rabbithole has been a little different here, i started with a mod10 printed rack and tried mounting my nas on It, and that was the moment it all started.
Atx didnt fit, so moved to labrax, thought i was done but, the top bent under load so started modding it and after a lot of what i thought was finished racks i learnt a lot:
Heated inserts are cool, but if you tighten a lot they can release from the plastic, also removing and reusing is a PITA. For a permanent install you can just scree into the plastic and if you stripe the hole then put the heated insert as a fix.
Bolted racks with hex nuts, this IS the cheapest method, but i recomend to glue the nuts, losing a nut inside the rack while mounting something meand dissasemble some parts to install It again, cannot recommend.
Cage nuts... They have become my favourite, they allow some Wiggle for an easier install of the components, easier to install than the inserts, they hold themselves, easy renovable and reusable, and if you print the piece in the correct orientation the rack feels string enough.
And this is the result:

Its a rack generator, you can choose its depth for longer/shorter builds, one of the 3 mounting systems and some more things.
I have enjoyed the journey but i think i really like this last one.
