My first 3d print project is a miniature version of a 1970's mainframe. It's basically a simple blue box with a black front panel. I thought i would glue the front panel to the box but that's not so easy with PLA. I see bolts and screw used for other boxes but i wouldn't want them to show on the front.
Any suggestions? You can see my first attempt at the shape here: https://olduino.wordpress.com/2018/10/16/3d-printed-case-for-the-olduino-370/
