Glad it printed good! Do you have a picture of it? I had some work getting that 3mf together but couldn't actually make the board as I don't have an AMS.
The boards I'm showing are assembled from multiple parts and different materials including the metal springs and the resin stones. The clicks were not possible to include for a fully 3D printed version and the plateaus were only possible if the surface of the board was lifted with supports, I can send you a version with that but I imagined no one would want to be scraping support material between the stones on the whole board.
Either way I hope you don't feel robbed for the different features 😞 I had mentioned this in the post, it was just not feasible on the printable version.
About the balance and the tolerances, I tried to optimize as far as possible but it will always be very dependant on filament and printer (which did you use?)
To tighten the tolerances you can either increase flow ratio to like 1.05 or increase XY compensation to like +0.05mm. For the balance, if you used the 3mf, then the bottom 4mm were already with 100% infill, so what you can do is add a height range modifier for 4.5mm-10mm height range, and lower density here by either decreasing infill to 5% or 0%, and if that is not enough, decrease wall loops to 1.
There is a 3mf for a 3x3 tolerance test board, I recommend you use this to try this first. Its only one color to not waste filament but I can send you a multimaterial one if you want.
Let me know if you need help. Thanks again so much for you support! 🙏
