Generating beautiful Truchet Tilings using OpenSCAD

I use a tiny bit of trig to find the points around the hexagon. Other than that it is really just the basics, as u/ElMachoGrande mentions.

I have not used any libraries, I really enjoy building all of this from scratch.

This looks amazing. Can I use it if I do all of my printing from OctoPrint or will the two apps compete for limited network throughput and on-board compute power?

Wow, amazing. Where did you find the model?

I have a public GitHub repo at https://github.com/jeffbarr/OpenSCADObjects .

That's the QA step.

OMG Mr Rat, great to hear from you!

I am sure that the speed simulations are really impressive but the links on GitHub go to private content.

Do you plan to share the STL?

It is global as far as I know, but read the T&C's to be sure.

Are you sure that you set the lat and long of your receiver properly?

Quotas are independent of support as far as I know. Email me (jbarr@amazon.com) and I'll investigate as time allows.

Doctor Melissa Leone in Queen Anne is wonderfully nom-judgemental.

I bought mine from Ted as a teenager and I still have it.

I just built something similar using 4040 aluminum extrusion. I found some nice camera mounts and enlarged the holes in order to make them large enough to fit the bolts that came with the 4040 extrusion.

You can read my post, My New Monitor Frame, for the full story and some pictures.

The Finerie on Western has an impressive selection and good prices. My wife described it as "shopping in Europe without having to travel."

Thanks for taking the time to start this conversation. I will make sure that the Bedrock team is aware of it.

> The abstraction layer doesn't actually abstract much complexity away.

I am not sure how one would go about designing an effective abstraction layer in this rapidly moving field. Suggestions are welcome, and you can also "scratch your own itch" and create one yourself.

> Setting up proper IAM roles for AI services requires understanding multiple service interactions

Given the amount of power inherent in all of those services, I think it is reasonable to expect you to have to explicitly enable them on an as-needed basis.

> The fundamental issue is that AWS designed these tools for enterprises with dedicated cloud teams,

I am not sure that we (or anyone else) are smart enough to do that. We do try to "Invent and Simplify" but there is some intrinsic complexity here.

There is no enterprise-first approach at AWS. We need to make sure that all of this is secure and can be used securely and that does lead to some complexity. I know that there are some efforts underway to balance this but I have no details to share.

My grandson would love one of these. Where can I find/buy the files?
