FreeCAD has a steep learning curve, I’ve only just started with it, but it seems to cover every possible use case. Good luck!
Just PLA, I’ve only had the printer for a week. It will make it though the winter but I’m not sure about the rest of this summer.
You can import an image to an image plane using the Image Workbench then scale it. After that it can be shown or hidden like any other part of your design so you can just trace over it.
Thanks, I ended up using a photo to get the profile into FreeCAD. It’s not a friction fit but with the phone in place it’ll never move.
The screenshot is a little lackluster but the video below shows it off better. The camera is an APSC sensor but the picture fills a full frame with very little vignetting. Up to 100x it looks pretty good but yeah, the DoF is literally micrometers thick.
