Hunter and I constructed the first prototype. It consisted of ten physical parts. The tray and nine plug-in modules. If you want to experiment along with us and this prototype, you can download the 3D plans from our downloads page.
Once 3D printing was complete, some parts of the tray were glued together with super glue. The modules could then snap into place and be removed as needed. While we hope the final paint head does not need any glue, we were experimenting with how things fit together and super glue offered us the most flexibility at this stage of construction.
Based on a several lessons learned with the Q prototype, we set out on a number of improvements for the next iteration. The main problem we are now trying to solve is how to suspend The Neural Jet from either an xy-table or a robotic arm.
