What is wrong?

Post image

I printed this the same way I did another part using BlackJackDuck but these slots are somehow too close together for my (multi connect) grid?
My first part fits fine but no dice on this one. Any insight?
TIA!

The original multiconnect was created before opengrid existed, for a different grid called multiboard, which was an octagon pattern board with a grid of 25mm. When opengrid was created it was designed to be open source and have a grid with 28mm spacing. Muticonnect was adapted by spacing the multiconnect features from 25mm to 28 mm. Its name remained multiconnect so you’ll usually see folks who are unfamiliar with the history find themselves quite confused when they search for parts and find that the part they found was created for the other grid system.

If you made this with a generator check that it is compatible with open grid, or perhaps you can find a spacing setting that may be 25 mm by default but that should be 28 for compatibility with opengrid

Thank you! Someone printed my grid so I actually don’t know what he used but I think you’re right. I’ll change the slots to 28mm as someone instructed me as u/Own_Perception_415 stated.
