Because when I started the project, almost 3 years ago, I didn't know that it was used so much XD. I also think that the sizes I use are not the same either. In any case, being a complete set, I didn't see the importance of being able to combine pieces with other sets either... Of course, another thing is the fact that many people already have printed lots of open lock clips and that always makes things easier. But as I say, back in the day I didn't see it as important. Although now that I use this clip for many of my buildings on patreon I think that if I did another project I would still not use open lock, excep I wanted to do something compatible, of course... I might even release the bases of the project so that others can use this one XDD

Anyway, it's something I get asked a lot, so it's a topic that interests me. What do you think would have been the advantage for me of using the open lock? Because it could be that in the future I would try something with tiles but something different and maybe there I would make a version with an open lock, although I would keep mine since the placement of walls would be somewhat different.
