Exciting moment! EAZYFAB, an on-demand 3D printing service provider from Kozhikode, Kerala, India came forward to sponsor a single print for the EXPLOG project and they did. Thanks to Sijah AK and Nabeel BA from EAZYFAB. I sent them the STL files exported from Fusion 360. It was printed with PLA and the print is very sturdy.
This is just a sample print to see if the sizes and placements are satisfying. I'll have to modify this further as I develop the PCB and add more modules. I still don't know how to make the buttons and haven't decide the placements of antennas. I'm thinking of 3D printing the buttons with either flexible rubber or PLA itself. If you have any suggestions on making good buttons, please let me know in the comments :)
