3D Experiments: DIY Trellis Soundboard

On wednesday 22 april I found on Adafruit a nice project to make a 3D printed portable Trellis Soundboard.

In this project they included the Stl files to make the casing. I downloaded them and started printing. At the same time I ordered the electronics items on the Adafruit website with some other items I already planned to buy.

First the Tray for the pcb with the 16 buttons. This item took 46 minutes to print.

Then the Top part. This item printed in 1:56 hours.

The next print for the big part, the frame. I had to cancel it while it was printing. Cura keeps the last settings available for next prints. In it I had set the infill to zero. This way the case was build with walls which had no connection to each other.. This would lead to a very unstable frame. Here are images of these walls.

The printtime was already 1:46 hour but it would take at least 5 hours to finished...So better start a new print..
The frame started good but half way it started to go wrong. Underextrusion. I did let it finished and I am thinking about covering the underextruded parts with glue. Strangely after the part of the underextrusion the best part was printed..very smooth and without mistakes. But I also think about a new try.
The print of the frame took 5:25 hours.

After this print I started immediately to print the bottom part. And that one came out very good. Printing time was 2:17 hours.

The next day I wanted to have another go with the frame part. I started the print at 6:30 in the morning. So around 12:00 am it should be ready.
And it did. The frame came out very good. Without mistakes in extrusion. Printing time was 5:25 hours. Here is the frame.
