Recently one of the magnet holders for my window shutters broke, and I thought I'd take a crack at designing a replacement to 3D Print. I'd never designed anything in CAD software before, so I had no real reference. I found FreeCAD extremely easy to use and intuitive. I watched a couple videos and followed-along with the tutorials, then started on my own item. It's a relatively simple 3-part component. I took measure…
Learning to design parts was a huge "unlock" for me. Wasn't just printing other people's designs. Great feeling to measure and design something then have it fit perfectly.
Previously I'd get my calipers first and try to model using the direct measurements. The key point imo of the video was to take photos and model based on the photos, and then correct the measurements with your recorded measurements second.
