I liked the design of the original thing, but it simply was not functional. The springs are too long to allow the blade to pass and the slider probably only worked if it could be printed with no drooping on the overhang. I only changed these two issues.

I printed two copies and I am able to reliable extend and retract the blade 100 times in a row on both. If you have any reliability issues it is probably the inside surface on the case or the rubber band choice/placement. Also note that it may not function without the case top and button.

I was able to make it work with two of the smallest size rubber bands from this package. https://www.target.com/p/u-brands-7-4oz-rubber-bands-assorted-sizes/-/A-16603894 I twisted them around each other before placing them on the slider so that both would make contact with the blade. See the picture. Please comment if
