Wood case with 3d printed insert for tonuino box

This 3d printed frame helps fix all the components for a tonuino (https://www.voss.earth/tonuino).

This is a 3 button variant, using one big push button and two capacitive buttons.
The electronic components are mostly screwed in only the dfplayer and the capacitive buttons are glued.

Due to the size of the push button I used, placing everything together is quite difficult despite all sides being on slides.

I printed it 5 years ago in PLA on my replicator clone: it does not need supports nor a well tuned printer. The grid for the speaker is composed of two files, the grid_holder and the grid_infill. These are meant to be printed together with the grid_infill having no bottom or top layer. This part may be easier to print nowadays as a rectangle with a cylindrical modifier, but I did not knew the technique back then.

Next steps that never happened: Install 1850 batteries and a charging/battery protection card. There is some place on the bottom for it but the bottom spacer_power has no feature to welcome it. Currently, I cut a usb cable and spliced it to power the arduino, the rfid reader and the dfplayer.
Using a powerbank with a switch did not worked well as the different cards are not powering up in the right order due to their different voltage needs.
