You are right, perhaps I should include it among the profiles. Thank you for your comment

Hello, many people have printed it, I personally have printed several but I have never had these problems and I have never heard of anyone with these problems. Have you tried thoroughly removing all the supports, even those in the internal holes? Note that all the ones I printed work as shown in the main GIF

Furthermore, could you post a video to illustrate what you mean by it not opening (perhaps you meant closing?) automatically

I cleaned up all the supports and brims but it took a lot of force to assemble and then pushing the button requires significant force and it won't spring back to the closed position without additional significant force. I think if you open up the tolerance on the sliding surfaces, it'll work much better. if you're making changes, you probably only need the brim on the spring. with a little more depth on the magnet holes, those probably don't need supports. it's not much time or material but difficult cleanup.

Thank you very much for sharing, I just posted the 4x4 Gridfinity version

Many thanks for sharing 🤗

Thank you very much 😊
