Experiments in 3D printing

Cliff,

I guess I missed where you did the ore chutes and made the STL files available. I have a spot where I could use two and will print them on a form 2. I find the quantity of triangles generated will have an impact on quality separate from resolution used.

Hi Al, here’s the link to the file:

https://www.largescalecentral.com/filesharing/file/view/13458/cjennings-h-n-ore-chute-stl

This is an assembly with all parts needed, including the brass rods and a bit of thread+brass rings to lift the main chute.

You’ll have to separate the parts for printing yourself, sorry bout that.

The counterweight, guide rods, main liftable chute,associated pulleys and yoke, are all optional. That was the fashion for mines in my my area of interest, but feel free to not print those and instead lengthen somehow the short fixed portion of chute. Just watch your clearances with your trains!

Cliff,

got your file and it looks great, thanks. not sure how to separate the parts in an STL file. I opened in solid works and all I see is one part that I cannot work with.

Please let me know.

Al,

If you need to just separate parts, you may just want to take a look at Tinkercad. It’s very cool for being “free”.

Al, you can use SW’s body-delete feature to separate / save out the individual pieces.

However, to save you some time (I didn’t know you used Solidworks) I just uploaded the SW part for you.

Bob, sorry for my tangents…

cool Bob

Next experiment, pole line insulators. I think the middle size is proportionally correct.

Electrical service parts I made including meter & box, head piece and tie off insulators.

Also made these baggage trucks

Nice. I have to order some clear green and blue filament to make these look right, though they do kind of pass for the ceramic ones…

I see both the clear green and blue filament coming off the spools?

Just saying!

I printed them with clear filament and painted them with Tamiya translucent green.

Printed the insulators in tan, painted, and dry-brushed. Not too shabby.

Pretty cool.

I’m thinking that 3D printing is REALLY changing the nature of the hobby. I can’t help but think how my modeling might have changed had it been available way back when.(https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-embarassed.gif)

Bruce, I agree. And the prices of printers are really dropping.

The big hurdle for anyone is learning new software for the 3d design, and you’d pick that up in a snap. And once you get over the initial hump, it’s fun! (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)

I wanna know why just one insulator (telegraph?) and why there is no flashing above the door framing?

I have been having fun with some Baggage carts

2 More carts and small Hit and miss engine and another person 3D printed

Dennis,

I know where the hit /miss engine came from. did you come up with the 3d luggage, or was this downloaded? nice job.

Baggage or Luggage got a couple hits on Thingiverse
