I adjusted the design tolerances to significantly reduce play and improved the position and length of the slide to minimize torsion. The print tolerances are extremely tight, so I recommend printing with a fully calibrated printer. Additionally, even after a successful print, make sure to lubricate the slides with something like body lotion.

Round off both ends of the slide after printing. I didn’t bother changing the design since it felt like too much hassle. The reason I’m writing with this kind of “half-assed” attitude is because this add-on honestly doesn’t perform that well. Sure, it’s more usable than the original, but it’s still kinda crappy.

I do respect the original creator’s idea, but honestly the original design shows almost no basic understanding of physics and has clear structural flaws. Treat this as something for toy use only.
