T-Track Risers

I have a small Shark Nextwave CNC I use for small projects. I get tired of having full spoil boards that need to be screwed down with t-bolts. This little solution allows me to have almost 80% of my slots open for hold downs, move them around easily to accommodate the work piece and size, and using TPU for Bambu AMS they are hard enough to maintain shape but still flexible and will not destroy bits.
