Simple way to improve magnet strength on a Tengyun V1

I don't know about you, but I love the Tengyun V1...it desperately needed an increase in magnet strength though. With this, I decided to look into it. Putting magnets in the center caps would not work very well because of the shape of the pieces. Replacing stock magnets isn't very feasible either. Then I went down the path of trying the same method that folks are using to increase the magnet strength of the RS3M 2020. Unfortunately, the caps on the Tengyun's edge pieces are pretty tight and it felt like I was going to break them, so I did not go forward with that.

Here's what I did:

I removed the caps from the corner pieces and placed stronger magnets on top of the three existing magnets. This is a bit weird as there is a plastic "stalk" in the way, so the magnets may sit at a slight angle, but it still works. I have 100 solves in it now without them moving, so I'm confident they will stay put. This method worked well, there is a noticeable increase in strength. That being said, I recommend using higher strength magnets as the impact wasn't quite drastic enough for me...it worked though! Maybe I'll look at stronger magnets in the future.

Update: The magnets did eventually connect to each other within the corner pieces. I had to go back in and glue them down, but it's still working. Added just a bit more magnetic strength to the cube, but still keeping it flexible/smooth.

How did you get the corner caps off? I don't want to pry too hard. It looks like they have plastic tabs that have to be pushed in for all three faces.

Edit: I got one corner's caps off but it took a bunch of prying with my fingernails. Definitely not easy to do.
It's much easier with a flathead screwdriver and a little force on the tabs. I may make a video on how to do this.

Hey sorry, just saw this response. Thanks for posting the video! Hope it will help some others! Like mentioned above, I had to eventually glue the magnets down as they ended up moving around in the corner pieces. Also, I think I would put even stronger magnets on it. It's a definite improvement, but could benefit from being even stronger I think. Hope you are enjoying the difference!

I haven't had a magnets moving around problem yet. Did you use the Cubicle RS3M 2020 magnet kit? Also as my personal preference the weak magnets compliment the soft turning of the puzzle. I thought the RS3M 2020 itself had adequate magnets while a lot of people apparently complained the magnets were too weak, though the magnet strength has no impact on my performance.
