Novation Circuit Tracks external speaker holder for IKEA Eneby Portable and others

The Novation Circuit Tracks groovebox is speakerless by design (unlike its predecessor Novation Circuit), which makes it kind of off-putting when you want just switch the thing on and do a little jam of yours. 

To overcome this drawback it seems that the original IKEA Eneby Portable black (https://www.ikea.com/au/en/p/eneby-portable-bluetooth-speaker-black-00476210/) is an ideal external speaker and solution for this - it is battery operated, matching color and design, with reasonable sound characteristics. 

The process of creating this was challenging as the Tracks is a box with non-regular angles all around the place. Fitting everything in, so the groovebox is still playable, yet the speaker holding still with all the connectors in the back being easily accessible wasn't an a piece of cake I've imagined. Also, the solution is printable even on Prusa Mini - that's the reason for the odd topology - so it fits to any 18cm printbed. The construction below supports even click-on adapters for other external speakers of your choice, so you can tune it up further.

Instructions:

1. Print all the parts with black PLA separately
2. Put the L/R corner part to your Circuit Tracks and hand-tune the positioning of the long beam (with the speaker adapter and speaker on), so you can fit your fingers between the upper row of knobs and the speaker
3. Glue the L/R corner together with the long beam, let it set
4. Hand tune the other corner position while on the Circuit Tracks, again glue together (ideally using clamps), let it set
   
   Note: the L/R corners and the long beam pieces don't match exactly the width of the Circuit Tracks - there is like 1mm space on each side, you need to tune the position manually during the glueing as described in the steps above
    
5. Take a thicker paper rectangle and put it between the Eneby speaker and the adapter (the vertical side) so the speaker really holds there - as the 3D print is not micron-perfect, it is better to have prints a little bit bigger and put some paper there for proper fit
6. Get some short TRS 3.5mm jack cable, connect and switch on the beasts
7. PROFIT!

If you don't like the corner pieces, I've attached the original SVG, so you can tune the shape as you wish.
