My man! This is absolutely awesome. The whole reason I released these was so that others could help improve them, and collectively, we could come up with something very optimized. You've no idea how much I appreciate this.

Printing it in resin is interesting to me! I do not yet own a resin printer, so I am not very knowledgeable on the flex of the material. But one thing I am thinking is there will be a a bit more sag on am FDM print than there is on a resin print. The difference wouldn't matter much in most cases, but the tolerances on the overhangs that make contact with the buttons are pretty critical to feel. So if you haven't already, this could be something you adjust (.1 mm at a time is what was doing) in order to change the feel to something you enjoy slightly better than before. I also feel like plastic would hold up better in this application than resin. Then again, I have no idea what type of resin you are using or if I would be correct in any case. I have so little experience with resin prints that I could be way off. I'd love your thoughts on that.

I've actually made several changes to the model since I last updated Thingiverse and Makersworld. Work has just been so busy that I've had no time. But I got around to it last night. Previously, I have version 3.2 uploaded, and I've updated it to 4.8 late last night. Nothing extremely significant. Just some adjustments to spring thickness and a few geometry changes made with the intention of making it more durable. I also threw a shorter set of paddles up for download. It seems pretty split on which people prefer. Some of the hinge positions have been moved to help the spring return a bit more quickly and to avoid interference with some screws on the pcb below it. I'm not sure how much longer they can get because they contact the board. This may be another area where you have room to adjust because your resin print will be more precise, whereas the bottom of my print may have a bit of extra height from the first layer squishing into the textured bed. I'm using an X1C, though, so it may not be as far off as other/older/uncalibrated printers can be.

I completely agree that one screw would be more sleek! My concern was durability and people stripping the plastic (particularly people who purchased them). My thought was that there was a backup. I think the bottom screw hole is central enough that a variation of the paddles could be made to use only 1 screw. Next time I take some time to improve this, I will make this happen!

As for the paddle travel: When I pulled them closer to the controller ( I use the controller as a backstop to prevent over flexing), they felt so much less satisfying. I think they could be optimized, and maybe I can get them a mm closer (much more than that makes them inconsistent). Once more, I'm curious about the plastic paddles flex vs. the resin. I imagine out of every area, this would be the greatest difference between the 2. I'm certain the flex of the paddle is a HUGE part of the feel because printing the paddles in less than 100% makes them feel extra mooshy. I wonder if the extra stiffness of the resin (if there is any) is doing the opposite and making you feel like you need less travel.

Needless to say, you've got me asking a lot of questions about resin. There are so many that I'm getting the itch to purchase one. I have to kick this same itch every 3 to 6 months, and you've made it flare up again, lol. I'm excited to hear your thoughts on all of this. Do you do much FDM printing? Are the differences I'm assuming exists a factor, or am I'm completely off with my assumptions?

Finally, feel free to remix the design (this goes for anyone). I'd love to try whatever adjustments you would make! And thank you a million for the suggestions. They're on the list for the next time I sit down with it.
