So, I bought a license of Plasticity late last year and for some reason had never used it (life got in the way)
Decided to get off my butt and use it today. It's really intuitive, especially since I can set the mouse view movements to equal Autodesk Maya so I don't have to think about it.
I have a set of ladder bars I bought for our 30 year old Toyota HiAce (Japan import 4x4 diesel van) that I'm going to put a basket on. Reviews recommended something on the ends of the bars before attaching to the uprights as bolting them tight can crack the finish and make them rust.
I made up some TPU gaskets, took maybe ten minutes from firing up plasticity until I was printing. Came out great! Bonus pic of the van they're going on (it's a work in progress)
