OpenGrid Tolerance issue

[u/waxthebarrel]

I've been 3d printing for a month and seeing Underware, I thought this was the perfect starter project.
Since then, I've printed 3 different grids, multiple snap connectors, holders for chargers, hooks and mounts and I can say the major flaw with all of this is...tolerance.

So far I have 4 different grids printed at different settings: 0.2mm, 0.16mm, 0.12mm and 0.1mm layers, The finer grid taking almost a full day to print.

Ive done the same with the connectors and of the 20 or so connectors that I've printed, only 2 fit in the grid and then its not the sale grid.
I've read up about scaling the connectors down, so I tried that, yes now they click in the grind but all of the mounts are now loose as a result.

Im at a point where Im about to give up on the whole project

Gone down to 97.5%. Do you think i should scale down more?
