October 2019: REDESIGN IS COMPLETE using laser cut ply for the front and rear panels to reduce the amount of 3D printing required somewhat, to reduce overall build time and also to reduce the time spent filing and fettling the keys, keyslots and so on to make everything fit and work smoothly.

The set of files I have just uploaded all refer to this easier to build crankless version. All the information is there for you to build one. This has an arcade FIRE button on the front right hand surface. Just hold the right hand end in your right hand, press this button with your middle 2 fingers; the drones and open melody string will sound as if you had started to turn the crank, then you start playing.

- A small amount of filing of the keys may be required but the laser cut ply parts require none at all.

- The keys can easily be renewed if you break one.

- Rear ends of the keys project from rear of keybox in a way more similar to a real HG.

- Keys shaped to hit front deck just before the maximum microswitch travel is reached. This should better protect the microswitches if played too hard.

I am working on a version of this with the previously described crank module. The build for that version will be 95% the same as this i.e. the extra wiring for the bolt-on crank module and slightly different code.

The play button does not have to be lime green, they come in many other colours!

Next project log will feature the crank version of this new design.
