I printed a couple of the brake samples at different infill densities. One was 10%, and the other was solid 100%. Both prints were too stiff. I wanted a model with many slots on the side, which should weaken the structure and mean less plastic to bend, but my program was generating errors when I attempted more than 11 slots. When I eliminated the slots, the "normalized tree" would have fewer than ten elements, but if I included a reasonable number of slots, like 9, the tree would jump over twenty thousand. I thought it was due to a minkowski() function running rampant, so I rendered an unholey model and tried to add the slots, but it still jumped to an unholy high number.
To stay under the low limit, I made the slot so wide that it went through both sides of the plug. When I entered an odd number of slots, it would generate twice that number. Using "9" resulted in 18 slots, which seemed like it would result in a thin slat without making it fragile. I also extended the slots further down so the end was not a solid piece and the slat could flex out with no restriction, which should also reduce the force needed.
I printed a model on its top so it did not require a lot of support. The resulting piece felt pretty rugged, but it may be prone to snagging on clothing. The results of tightening a bolt were a relief because I was able to insert the brake, hold the exposed part with one hand, and tighten a bolt with the other. The brake held well, and I can stop messing around with this detail.
