$3D PRINT: DESIGN FOR 1st COPY SUCCESS Design log video describing my approach to getting a functional print to work the 1st time. 3D printers are excellent for producing functional parts for the various project around my home.... however, care needs to be taken to ensure the 1st print is useable! Rain gauge mount.
