A huge 3D print - The case for the Behringer 2600 Synthesizer

Behringer offers an incredible value for money synth with their ARP 2600 clone. The only thing which I was missing, was the vintage styled housing of the original 2600. Yes, I could have build a wooden housing and string it with tolex, but this would have involved too much time and the price for such a case would be redicoulsy high. That's where I had this crazy idea to print such a case on a 3D printer...

A huge 3D printer

First I realized, that my trusted Prusa Printers were not able to print such a big housing. So I had to look for an according printer which is cappable to print such large objects. Under all cirumstances, I wanted to avoid glueing parts together. Luckily I found exactly one 3D printer model which was reasonable priced and offered the required print volume: The Creality CR-10 S5. The printer is not too bad, but required a lot of modifications to become a reliable work horse:

Changing all fans
Reinforcing the vertical (Z) beams with additional beams
Reinforcing the Y stepper motor mount
Installing stepper motor dampers
Installing a big 220V silicone heat bed
Exchange the extruder
Align and protect all wires

The printer is not the fastest, but it does the job very well. Printing the 2600 case takes about 2 days nonstop printing and the result is amazing.

The housing for the Korg SQ-1 Sequencer

Since I wanted to add a extra feature, I included an optional housing for the SQ-1 sequenzer, since also the original ARP 2600 came with an optional sequencer:

All in all I'm very happy with the outcome which is by far better than I would have expetcted to be possible with a 3D printer.
