why are 3d printer-brained MFs so bad at design engineering ?

i was trying to figure out why i was so annoyed but i realise if i had to do even 4 different printed revisions and also if his last concept was the best I had in me and ALSO if it needed to be such an exotic material to be strong enough i would think i finally have lost the plot. also he doesnt even add a handle to the other end and keeps the shitlord recessed handhold ?? and also can't figure out or envision making it a permanent fixture and makes it semi-permanent when the concept was originally meant to be as easy as a snap fit? and designs the snap fit in like 6 different shitty ways before changing the design in the most half assed way possible? and ,,,, 500,000 views?? this is your hero?????
