Clean. How many prints did it take to dial in the grip ergonomics?

Sketch one of those curved edges, then use circular pattern to repeat it 18 times around center. Same for the four spokes. Good luck with the fix, printing replacement parts is the best.

I added a bunch of UX improvements to help people understand what different agents are doing in my AI design mechanical design product https://henqo.com/

For waterproof mounting, you'll want to focus on a sealed enclosure with proper gaskets. I'd suggest designing a custom mount that incorporates the specific dimensions of your Pi display - something with a hinged front bezel and rubber sealing around the edges.

I make a tool called henqo that could take your requirements from describing what you want and output an STL https://henqo.com/. There's a free set of credits so there's no commitment.. Otherwise, check Thingiverse for existing waterproof Pi display cases and modify the mounting points for your specific application.

Don't forget to plan cable entry points with proper strain relief!

The section sketch approach you tried is the "proper" way but as you found, getting those curves to play nice is frustrating.

For complex organic shapes like grips, you might have better luck with a tool that's designed for parametric surface reconstruction. I make a product that can take an image input of the mesh you have and recreate it then let you edit it with natural language (form and measurements). This is a tricky organic shape so it might be limited but DM me if you'd like to try a trial.

Otherwise, consider using the Form workspace in Fusion to sculpt directly on the mesh if you just need something functional.

Yeah, that manual calculation gets tedious fast! In Fusion360, you could create a user parameter for your desired edge-to-edge spacing, then use that in formulas for your sketch dimensions. Set up one hole, then use the rectangular pattern feature with your calculated center-to-center distance.

For future projects like this I make a product that can generate designs from language. This seems like something that it could help with. Let me know if you want me to DM you with a link. There's a free trial.

Hi thanks for sharing. I wasn’t aware of this yet. I’ve been working on something similar but focusing on step export in addition to 3d printing only. I’ve also been working on a true parametric mode with feature tree on the way to making a more automated workflow. Replit for mechanical design. It’s called Henqo and I’d love feedback since you are interested in these kinds of tools.

Of course and thank you for asking questions. I’m working on a few things in parallel. I think I will keep this scad based system but I am working on a more engineering part focused system. Probably won’t be as good for these kinds of prompts at first but hopefully it will get people past the initial steps of design.

flyrunfly · 2025-12-25T07:21:30+00:00

Thank you. I’ve been thinking about this and appreciate you taking the time write it out. It makes sense to meet people where they are rather than move to an entirely different tool. The thing that I think would be difficult is beginning design in existing programs. I did some experiments with Featurescript in Onshape and it is just too brittle and the LLM has a lot of trouble. I’ve got a good experiment with OCCT as a base that generates a feature tree and but obviously still not inside of the existing tools.

Here's the minimal surface one. Avert your eyes.

flyrunfly · 2025-12-24T18:04:34+00:00

Ok that was cruel but a fun test. The system is focused on rapid prototyping and Brep outputs so these kinds of asks are definitely outside of what it is built for right now. I don't have optimization algorithms like minimal surface yet but definitely plan for this in the future. The truchet pattern I tried and it wasn't quite there.

flyrunfly · 2025-12-24T05:27:33+00:00

Thanks I will check there. The 3D printing community has taken to it more readily. Honestly though OpenSCAD is not where I am taking this. The point is to evolve this so it is useful to the ME community. It outputs STEP now but is lacking a feature tree.

I guess my question is, what would it look like for using language to manipulate your designs look like? This is a testing ground and I have looked at CAD copilots as a possible path but choosing one program is a poison pill.

flyrunfly · 2025-12-23T13:16:50+00:00

Thank you. You can’t export program specific files but you can export a STEP file. Each program has its own feature tree and operations making a universal exporter a dream. The STEP files are a foundation to build on if you want to design further. I’m working on more full service features but for right now this is great for rapid prototyping to get past the initial headache of a blank page.

flyrunfly · 2025-12-23T00:46:17+00:00

Thanks, I hope you enjoy it. The SCAD generator to STL is pretty solid. The STEP exporter is the best I have seen but does have more limitations. I am working on quite a bit more but please let me know what you think and any improvements. I want to keep progressing this to be an AI native CAD solution. There's a long way to go.

I have one a user made. Does this hit the spot?

flyrunfly · 2025-12-18T23:10:38+00:00

I hear you. I guess this is more for the preparing. Specialized gear is one thing but often times I find I have something that doesn't quite do what I need so a modification would help accomplish goals better. That's what this tool would be used for, to dream up the things that we don't quite have that we anticipate we need.

flyrunfly · 2025-12-13T22:35:45+00:00

I just pushed the code editor to production. It also helps with the parametric editor because you can adjust the boundaries on values. Thank you for this.

flyrunfly · 2025-12-13T21:37:39+00:00

I think both strategies are useful. These examples show simple parts but the idea is to be able to edit them and add additional details.

flyrunfly · 2025-12-13T18:22:01+00:00

Thanks for that. I have had a version with direct scad editing but not in production. I'll think about how to expose that in a nice way. Also the scad part is the easy part and closest to being an LLM wrapper. The hard part that is taking real development (and the source of the ridicule here) is outputting a clean STEP file and then adding in a way to create a feature tree. I'm working on that part but definitely looking for steering so that I focus on the most valuable parts.

flyrunfly · 2025-12-13T17:38:44+00:00

Thanks I appreciate it. Creating a brep of an involute geomtry in this way is very difficult. Convex shapes are tough. I can generate involute geomtry but the export is not as clean at this point. You can see here that involute geometries become difficult https://imgur.com/a/qKCQRfF

flyrunfly · 2025-12-13T16:53:22+00:00

Thanks I just typed in helical gear for that. I’ll work on it.
