I am a physicist enjoying the usefulness of 3D printing and CNC lasing or milling.
I have a cheap China based printer (Geetech i3 X for ~350€) which I upgraded with M8 hardened steel rods, trapezoidal threaded rods and Igus bushings. Other improvements including Z-nut-assembly, X-carriage-assembly and minor parts are printed and designed by me. Now the printer has a good printing quality.
Measuring STLs: Some people print out the files first and check the dimensions after printing. I'm using this program to inspect the dimensions of the models before printing: https://www.3d-tool.com/en_free-viewer-download.htm (I'm not affiliated with this company.)
Lasing and Milling: I use Inkscape and the Jtech Photonics Inkscape gcode plugin (Remove "G1 X0 Y0" in "laser.py"!). FlatCAM can be used too. It can import various formats including gerber files used for PCB processing.
Regarding Tipping Thanks a lot for your appreciation, but designing useful parts is my hobby which I do If I feel like it and if I have time. A tip would be kind of a pressure. :D Nevertheless, I like and follow the Idea of open source and I keep doing stuff for free.
