A fantastic project Peter. Amazing CAD work and rendering. How can we help? If you can provide two or three pain points that you need help with, that would be great way to help direct assistance. 

Looking forward to seeing your project hit the prototype stages.

Thank you!

My biggest challenge to building a physical working prototype is the electronics aspect of the design. Although I have left some physical space for electronics to be implemented in the CAD model, I'm not sure where I would start with the PCB design and the logistics of power supplies and motors.

Secondly, creating the body of the prototype model would be done via 3D printing but would have to be at a smaller scale due to the large filament cost. This has limitations as a scaled down model won't provide a full idea of the accessibility and user experience compared to printing a full size model. Ideally, breaking the model down into pieces and having access to a large 3D printer with supply of filament would allow for a full size model to be created.

Hey Peter,

Really cool project and I love the aesthetic! Having a bit of 3D printing experience myself a couple of things I'd recommend making it clearer in your presentation if this has the features that are associated with an easy-to-use 3D printer. 

What I mean is that something that people who are looking at a 3D printer for the first time won't understand is that the bed being level is essential for good prints - a quick explanation of why your design resolves this would go a long way in making it clear that you have the answer. 

The only other note I have is in your exploded view of your extruder and hot end, it appears to me that the boden tube is broken up into 2 smaller pieces and 1 longer piece that goes out to the filament chamber. From a technical view, you're now hoping the filament doesn't jam on an extra 2 components that are prone to deformation with their proximity to the hot end. 

I really look forward to seeing where you take this! Good work.

Hello Alex,

Thank you for your feedback!

I agree that explicitly mentioning auto bed leveling as a feature is a good idea - especially since a level bed is such an important aspect of first-layer adhesion (and therefore a successful print). Someone new to 3D printing will not want to experience a failed print and then have to manually re-level their bed.

Regarding the extruder and Bowden tube - I see what you mean. Ideally the PTFE Bowden tube should end at the top like it currently does but instead enter a single metal tube with no seams or locations it could get caught. Eventually funnelling into the hot end.

Thanks again! I appreciate your feedback and interest in my project.
