With my Shapeoko 3, I wanted a version of these hold downs that didn't go as high above the material, as they interfere with my dust collection shoe. This is my attempt to solve that problem. If there is interest, I'll try to repeat the remix with the short and long versions of the hold-down bar. I usually use the medium one, so I don't need the others.
EDIT:
As commented on in the comments section, the original design de-laminated after about a year of use. I've re-designed for my purposes. This new one is smaller, using less plastic, but doesn't have as much of a lip to delaminate (I believe). These in PLA have a slight flex in them as well, which works well for me. I position properly, and flex until the flat part is just about flat, and I feel I have enough pressure. Check back in a year to see if this one also fails on me. Whenever I really need a strong hold-down, I use the original ones I derived this design from.
