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. U nder all cirumstances, I wanted to avoid glueing parts together. Luckily I found exactly one 3D printer model which was reasonably 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 textured surface looks almost like tolex:
The housing for the Korg SQ-1 Sequencer
Since I wanted to add an extra feature, I included an optional housing for the SQ-1 sequencer, 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.
