crush ribs: "a set of very small standoffs that deform as a part is press-fit into them. Instead of a piece of hardware making contact with the entire inside surface of a hole, it makes contact only with the crush ribs. Press fitting a part into crush ribs is far easier (and more forgiving) than trying to get the entire mating surface exactly right." tried this out and... it really does work?!
"a JupyterLab extension for 3D geometry modeling with collaborative editing support" this is cool but how come I didn't know about Open CASCADE until today
"Instead of the shafts of a conventional loom the Weberknecht-loom has a pattern device that is equipped with pattern discs. These discs have small raised rings on their surface, the warp lifters, which will lift up the warps threads when in working position. Otherwise the thread remains lowered on the larger centre ring." extremely cool idea, free 3d models and instructions, i wanna make one this summer
