I've been designing standard boxes for a pegboard project and I have tried to make them parametric where possible. Most of this I have printed out of PLA plus except the pins i have been making out of resin because of how small they are. The pins are a nice press fit with the settings on my printer but you should test out a few to get the fit right. The wrench sets I did use a .02 offset for one and a .01 offset for the other. The .01 offset seemed to work better for my printer
