mark, please post pics when you get the frog family done.

@brenda
I am currently printing a 200% size froggo in what is labeled as "fast color changing" rainbow filament. I don't think it is changing color fast enough for this print job. I will probably end up with a golden froggo.

I took a short video of it being printed...

It has about 2 hours remaining on the print job. The total print time is 6.5 hours

@mark That's going to be so pretty!

I know I've told you this before. I love these. Make LOTS!

Just finishing up...

The final print.

Ribbit....

Excellent! Fun colors! What size and color next?

[mark]

@brenda I'm printing 50% sized "babies". Four of them at the same time. 1.5 hour print time.

[brenda]

@mark Your frog family is growing by leaps and hops.

[mark]

@brenda lol

This is it. I am done with these critters for a while.

Currently printing a 300% version of this Ghost ship in the color changing filament. It's a 26.5 hour print job.

@mark Fun froggo family you've got, Mark.

Your ghost ship looks like it belongs in an aquarium with lots of tropical fish swimming in and around it.

The 26 hour ghost ship print failed about 1/4 of the way through. Corrupted G-Code it seems. I will try again someday but I have other projects in mind first.

This is the current print happening right now. It has about a 13.5 hour print time. It is a case for a Raspberry Pi 4b 4GB with a HyperPixel 4 capacitive touch screen. I am going to use it for the Octoprint app running under Linux to remotely monitor and control the 3D printer. The system will have a hi-res camera watching the print bed. It will ride along the Z axis so I can monitor the nozzle visually anytime during a print.

I laid all three parts out to print at the same time. It downloads as three separate files.

I am printing it in Jet Black.

The Raspberry Pi case turned out good after a couple of failed attempts to print everything at once. I separated them into 3 different print jobs and it worked much better. Not crazy about the case design.

In the latest development, the Raspberry Pi is now feeding the printer and streaming video of the process.

I worked on the Raspberry Pi and the HQ raspiCamera until 3:00 am this morning. The time involved included the fact that I was attempting to install a cooling fan which involved some soldering. But then the supports for the fan broke off in the case, and a few choice words were spoken. De-soldered. No fan for now. Installed heatsinks. I tried for a long time to get Octoprint to work with the camera, but I ended up frustrated and decided to go with the mjpg_streamer method. The process involved compiling mjpg_streamer and creating a script so it auto starts on boot. Yes, that was easier then getting Octoprint to see this camera. lol I could find very little out there about it.

In any browser on my LAN, I enter http://raspberrypi.local:8080/stream_simple.html

The first print I did with the Octoprint controlling things was of course an articulated octopus.

@mark The froggos are cuter.

[mark]

@brenda Of course!

The 300% scaled Ghost Ship took 31 hours to print.

[brenda]

@mark That's very cool, Mark. What are the dimensions? Will it fit in an aquarium? I can picture fish swimming through the openings.

[mark]

@brenda a collection of prints I have made showing size differences.

[brenda]

@mark You're gonna need a really big aquarium for the ship! LOL

[mark]

@brenda The Ghost Ship is a heading to my Uncle as a decoration for his pool deck porch. I am also printing a pretty cool looking sailboat for him.

Last night I printed this "Galaxy Purple" vase for Mrs. Mark. When you spin it, the color varies as the light reflects off the different angles. It is thin and translucent, yet water tight. 3 Hours to print.

How much does a print job cost in terms of materials? Maybe in $ per hour?
