Post a picture and dimensions you need for this knob.

I have Black PLA that would probably work for it.

[Rainman]

hmmm. Picture of a knob. I'll look for one.

But let's see. . . If there was a place where you could buy the program for an exact replacement for something, then you sell the digital download, and you make. . .

Another Rainman million-dollar idea! My wife told me that's how she downloads stuff for her embroidery machine. So, it's been done, but maybe not yet for 3-D printers.

@rainman Can you tell which one is the original part and which is the 3D printed part?

The designer used a wood infused PLA formula. Sanded, stained and finished.

The one on the right - toward the tips of his fingers.

@george-k interesting. Why do you say that?

There seems to be some buffing and wear at the base. Of course that could be an artifact of lighting.

I have seen some pretty convincing objects printed in wood filament.

BTW, I have no idea which is which in the photo I posted. lol

@Aqua-Letifer I printed my first miniature today. This might just jump start my interest in our D&D saga. I apologize for lack of enthusiasm and participation. I hope to free up some time to start participating in the adventure. If you haven't already killed off my character. lol

This miniature was completely surrounded by a wall of supports. I should have taken a photo but was too eager to see what was inside and started the process of peeling away the supports to reveal this surprisingly detailed figurine.

I have since cleaned it up more using an exacto knife and sandpaper. The horns and spikes are more defined and have had more support material removed, etc. Then I turned it over to my daughter for final post-processing.

Peeling away the layers of support I was under 5x to 10x magnification. I could see the stiletto heals and was very surprised that I was able to preserve them. They are so thin, as are the spikes and even the shaft, of the mace. A very young, steady hand needs to finish this. I am happy to pass it on to Melissa.

What is strange about this model is that I had to scale it 500% to get it to print this size. I cannot imagine how small the original is. I need to print one just to satisfy my curiosity. Then I will print a 1000% scaled version. lol

First decent time-lapse of a 4" Fan to 3" duct adapter.

Still working on the Time-lapse settings to try to produce a smoother video.

Much better time-lapse. Almost cut the top of the head off. Too close to the top to call this good. Also working on Image quality. Working with the Raspberry Pi HQ Camera. Everything is set to default values. I am working on a new camera mount that rides the Z axis (Vertical) following the print nozzle. It's another effect to add to the time-lapse to make it more interesting.

I started 3D printing this turntable Friday. Just finished the final parts of the tonearm about an hour ago. I haven't even optimized the cartridge setup, just a rough alignment, set the tracking force at about 2 grams, a makeshift ground cable, adjusted the gains in the preamp, tested the speed, and played some Pink Floyd...

Pretty impressed with it.
