I’m not from an English speaking country, so please bear with me, I will try my best to make me understand.
I’m considering making the 525 25,4mm update, but before starting printing I like to analyze by CAD what I’m about to print. That also gives me a very good idea of how everything is assembled.
So while doing this, one thing felt weird, there is a difference between corner tube centers and middle tube centers.
Here the distance between centers is of 29.4mm
There are some tolerances, 25,8mm tubes can fit, so a 0,4mm offset.
Everything tight down theoretically will give a center-center distance of 29mm
But here the distance between centers if of 27,3mm
What am I missing?
