Fully customizeable pen case with label on the bottom. Due to the construction the upper part snaps over the lower part. No further parts are necessary. I use ist for:
1st section: chalk
2nd section: glasses and a whiteboard marker
3rd section: Pen certainly - guess my profession
You can choose which part (upper, lower) you want to gererate.
Please use the scad-file and customizer direct in openscad and the newest openscad version or "Thingiverse customizer".
One example with length = 145 mm, width=66 mm and no label at the bottom is already available as STL-file: The wall tickness (customizeable) ist 1.2 mm . So the inside is about 5 mm smaller then the outside dimensions.
Please print the upper part with the elliptic side to the heat plate! So you don't need support and it is more stable.
