Re: Inspiration needed

If you are a member of the 16mm Association, you can download issues of 16mm Today back to 1985, perhaps in a flick through some of those you will find something you really like? There's also the index, where you can look at a list of drawings from 16mm Today and get a link to the issue that include...

Re: Weak Bachmann Lyn motor

If the worm wheels are standard size, then maybe a motor with smaller diameter worms might give more thrust. I'm hoping that assumption is valid. With worm gears, the gear ratio is dependent on the number of starts of the screw, not the diameter of the worm. E.g. a single start worm used with a 40 ...

Re: Can you tell what it is yet?

Hi. I am not sure if you found that video or made it fort his example? However it took me hours to follow that video and I still ended up doing things a little differently as I could not see how some of the things were done, presumably keyboard shortcuts? Yes, I definitely used keyboard shortcuts i...

Re: Can you tell what it is yet?

Out of interest I have just had a go with TinkerCAD, your results look brilliant for what a basic set of tools it gives you. I haven't seen a good way to do the flare on the dome in TinkerCAD. This is how I would do it in Fusion 360, its very easy, at least when you know how to do it. :lol: https://...

Re: 3 D Printing 16mm models

Is there a way to view the slicer's output, layer by layer? If the odd face issues are visible in the sliced output, you know it's a slicer settings problem, otherwise you would know it's some problem with the printer not producing what the slicer software is expecting.

Re: My Flashforge Printer Journey.

Standard spool holds 1KG.. Don't want to be pedantic, but as far as I know ( unless flashforge is different) a standard reel weighs 1Kg, BUT the plastic reel itself weighs approx 250g, so their is only approx 750g of actual filament on the 1Kg reel. I've never got less than 1kg of plastic on a spoo...

Re: 3 D Printing 16mm models

As far as I know the "soften edges" just alters the shading so that instead of sharp edges you get a smooth transition between faces. Blender has a similar thing, enabled by right clicking on an object and selecting "shade smooth." These only affect the shading, not the actual tr...

Re: 3 D Printing 16mm models

The problem with printing them this way up is that the roughest parts of the finished item are on the top where they are so obvious. I would cut the horse in half and print the bottom half legs up and the top half head up and bond the two parts together. This way you get a good finish for the top s...

Re: A different 3D printed diesel

Different programs assume different units, so you often have to do some scaling to get things matched up. I often just try variations of 10/100/1000/25.4 until things look about right. Also need to consider if you are working in real-world scale or model scale, Makehuman will do things in real world...

Re: Gravity running on the RVOM

I was thinking that they might self steer around curves and avoid the flanges making contact with the rail (and causing friction) - yet to see if that has any impact. Without a solid axle connecting left and right wheels you don't get a good steering effect due to a tapered tread, there are lots of...

Re: 3D Printed LKM NS2f

That is a nice looking loco. Quite interested in the jackshaft and cranks, did you end up with any tight spots that needed attention or did everything just fit right off the printer? I've not attempted a loco with con rods, but looking at this I think I am inspired to incorporate con rods on the nex...

Re: 3 D Printing 16mm models

That text came out quite nice, you could do a mirrored version of the text that could be used as a stamp? Might be better off in a more flexible material like TPU, but even then I think you would need to do manual touchup. You could even include a slot that fits around the box on the side panel for ...

Re: Using Fusion360 to produce drawings for 3D printing

At 1:52 in your video, the Select arrow magically becomes an Orbit tool. I did eventually spot that the LH tool at the bottom of the screen had gone a bluish colour but it took me quite a while to notice. I presume you used some sort of shortcut, off screen? Shift + middle mouse button allows you t...

Re: Using Fusion360 to produce drawings for 3D printing

Sorry, me again. I can't get the Offset to accept the full expression in your example. ( 3"*sm32scale ). When I do it, the 3 by itself is fine and draws a square 3mm outside the original. 3" also works and draws a square 3 inches ( 76.2mm) outside the original. However, as soon as I add t...

Re: Using Fusion360 to produce drawings for 3D printing

That looks interesting and quite logical. My burning question - is it idiot-proof? Will I be just as likely to produce an unprintable shape with Fusion as I seem to be able to achieve in SketchUp?
