Layout in a shed Part 2 - 3D printing

[Trainshed]

Hi all,

just thought I would share my 3D prints with you.

 

Started off with a Creality Ender 3 Mk2 (FDM) and had been aching to make a linear point motor mount for a 9g servo.

What you see below is about version 15 or so!

 

The purple bit at the bottom is a slide mount, so that I can remove the motor mounts without the need for a screwdriver.

 

 

And here is a batch ready for installation

 

 

Only another 45 or so to make and fit!

 

Next I tried my hand a making a wagon. I found a generic chassis online, designed my own body on Tinkercad and gave it a go on the FDM printer.

 

 

It came out alright, but the layer lines are very distracting.

 

Then I had a go at an MWA that I downloaded. I had to cut it into pieces on Tinkercad so that I could print it in pieces.

 

 

Again with the layer lines and the FDM printer is not that good with fine detail, such as the bogies.

 

Even so I persisted and made a batch of wagons.

 

 

At around this point I decided to get a Resin printer (Elegoo Mars 2 Pro) and have a go at better bogies.

 

 

This is with the supplied water washable Resin which is no good for bogies, as it is very brittle and broke when trying to fit the wheels. I then tried Anycubic ABS like resin and this was much better.

 

Now that I had a decent resin, I tried a bigger wagon. This was download from Thingiverse, bot was a New Zealand Railways wagon, so need a lot of fiddling on Tinkercad to Anglicise it to make it look like a UK wagon. I know we don't have this wagon in the UK, but I liked the look of it and so gave it a go.

 

 

So I have reached my 10Mb limit. more soon

 

 

 

 

[Trainshed]

Back again.

 

Printed about 8 of these wagons, but here are a couple on the layout.

 

 

Next I had another go at the 16Ton Minetal wagon chassis I tried on the FDM printer.

 

 

 

 

This was designed on Tinkercad and as you can see, has much better detail than the FDM printer.

So I printed the bodies in resin.

 

The body had one coat of Halfords grey primer. I also had a go at my own magnetic couplings.

 

 

 

Just a couple of the 18 that I printed. The stripe has been painted with a draughtsman's bow pen. I still need to paint the chassis and add decals.

Next I tried something else. A 21 Ton Mineral wagon and a Dutch wagon.

 

 

21Ton on left, Dutch on right.

 

And here are a few 21 Ton wagons on the layout. They need to be painted and have decals added.

 

 

This is the self centreing coupling mount that I devised for the wagons.

 

 

When I saw that Hunt Couplings were doing knuckle couplers, I thought I would give it a go as well.

 

Some very cruel close ups of the couplings

 

 

 

 

That's all for now.

 

[Trainshed]

Me again.

Then wanted to make some water carrier things.

This is just off the printer

 

 

Painted and sign added

 

 

With the water containers added (printed in Jayo white ABS like resin).

 

 

A couple with the tops cut off and filled with stuff to resemble dirty oily water.

 

 

Then designed some picnic chairs

 

 

Then downloaded a wagon from Cults ( you have to pay for these ones)

 

 

Chassis printed in Anycubic black ABS like and body in Jayo grey ABS like resin.

Then had a go at End Of Train lamps.

The lamp LED is a 1.8mm and it is next to a 3mm LED for reference.

 

 

Then some cable reels designed on Tinkercad mounted on stands downloaded from Cults.

 

 

Also downloaded from Cults, some wheel stands

 

 

 

Next came a major project, a Rail Head Treatment Train. Also designed on Tinkercad.

 

 

I know the wagon is not correct, but I am not sure if a 3D printed spine wagon would be rigid enough. Also, as I was designing it from photos, the dimensions may not be correct, but as long as it looks ok I am happy.

 

And here are some of the parts printed.

The generator?

 

 

One of the tanks (still need to be revised)

 

 

The thing with four holes?

 

 

 

 

 

 

[Trainshed]

And finally some storage lockers?

 

 

 

That's all for now, hope you liked what I have done. See you on the flip side :-)

[alangdance]

are any of the STL availble for download. They are very nice.

[Trainshed]

Hi alangdance,

I can try to add them to Thingiverse. I will update this thread if I am successful.

[Trainshed]

Hi again,

 

Sorry, didn't confirm which ones you wanted added.

 

I have added the RHTT bits to Thingiverse, but as I am a new user, it waits 24 hours before adding them for download.

 

"Rail Head Treatment Train Components"

 

As I said above, It is not an accurate copy, just my version taken from photographs. I am a "it looks ok" kind of modeller.

 

If you want any others, just let me know on this forum.

[Trainshed]

Please be aware that I can only submit the ones I have designed, as the others are a paid download from Cults,

[alangdance]

Thanks. I like the mineral wagons and the servo mount.

[Trainshed]

Hi alangdance

I have uploaded the servo mount and the 16 Ton Mineral wagon to Thingiverse.

If you have any questions, please do not hesitate to ask (not sure how to answer on Thingiverse, so here may be best)

Have fun.

Nicely done! Small aside, they’re the wrong bogies on the MWA - the flat-top TF-25s are fitted to the JNA-A, you want ordinary TF-25s for the MWA. 

[Trainshed]

Hi njee20,

Thank you for specifying the correct bogies, but these were the ones that came in the MWA package from Thingiverse. I am not able to find an stl file for the ordinary TF-25 bogies and my design skill are not quite up to making my own.

[njee20]

I struggle to believe that - you’ve got some lovely prints and some nice designs! 
 

some decent dimensioned drawings of them here: http://www.innobogies.de/en/axiom ln 25 en.html

[Trainshed]

Hi njee20,

Thank you for the link to the bogies. I am presently reprinting the MWA wagons in resin, as I am not happy with the layer lines of the FDM printer. Just waiting for the first one to finish as I type., so may have a go at designing the correct bogies if I can find the time.

 

[njee20]

Yeah you’ll obviously get a much better finish. I’ve only done the MWA-B (and here in N gauge), but shout if you want decals!

 

[Trainshed]

Thank you for the offer, but I am doing the "standard?" MWA with the rectangular sign. I have had a go at designing it on Microsoft Word and it looks ok. Just need to print it onto decal paper and give it a go. I will remove the green background and print onto clear decal paper.

 

Your MWAs look good. I used to model in N gauge, but it was a bit too small for my sausage fingers and my eyes.

[njee20]

Be aware that on clear decal paper the yellow will be invisible. I’d stick with the green surround I’d say, and use white-backed decal paper.  Or slather in graffiti like the real thing. 

[Trainshed]

Hi njee20,

thank you for the heads up regarding the yellow graphic.

[Trainshed]

Hi again,

just an update on the resin printed MWA wagons.

Only printed four so far....another four to go!

Just stuck the man there for scale.

 

 

 

I had a fiddle with the original bogies and removed the flat top. I also had a fiddle with the shock absorber mounts, but probably too small to see.

 

 

 

Also downloaded these the other day.

 

 

Oxy-Acetylene bottles and a compressor. Had a fiddle with the compressor to make it less toy like, as it had 5 spoke alloy wheels! 

[Trainshed]

Hi all,

sorry for the long period of nothingness, been decorating.

I would just like to issue a warning for anyone thinking of plastering their ceiling without eye protection....DON'T DO IT.

Wet plaster with a PH of 11 - 13 in your eye is not very nice, also my trip to A & E at 2 AM in the morning was not very pleasant either.

Anyway back to 3D printing.

I did receive the Dapol spine wagon set for my Birthday and so set about redesigning the RHTT bits to fit.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

They need a little bit of a clean up and then, when I get a few moments spare, a coat of blue paint. I have ordered a set of transfers from Railtec (£14.50 gasp!) and will fix these when I pluck up the courage.

 

That's all for now. Take care.

[Trainshed]

Hi again,

forgot to add that the control panel in the picture above is removable, so that it can be painted and then inserted.

I will also upload the stl files to Thingyverse when I get time.

also need to find the appropriate paint in acrylic. Phoenix do it in enamel, but I prefer water based paint.

 

TTFN :-)

 

[Trainshed]

Hi. sorry for the delay.

 

I have uploaded the STL files to Thingyverse. have fun :-)
