So, first of all thanks for your answer.
-the school rule was there just to give you an idea of the size (for the final measure i will obviously use a calipper)
-i already have the photon, i'm just wondering if it can achieve such small features
-the stereo is 1000+$ worth, so no new one (plus it's not mine, i'm just looking if i can model/print such things).
My main point was, how do i model this thing? I'm guessing modeling a cross section, then extrude it, then adding the features. Am i right?
