Please post photos of your succesful aeromodelling/workshop 3D prints together with any relevant helpful information you may like to pass, perhaps even links to stl files, oops there's another one for the jargon buster.

Nothing here yet so I'll make a start.

Having managed to print the test cube and used up my sample of PLA I decided that ABS woudl be the material of choice. This may not turn out to be so but we have to learn! Next peice to print then was something as an ABS test peice but also useful.

These are guide lifters for my windows, I haven't been able to get any for years, so I made my own.

Here's a selection of things I've 3D printed over the years...

quad.jpg

Most of the items in red (props excluded) are designed and 3D printed by me. They include motor bumpers, Aerial guide, plate spacers, VTX tray and XT-60 holder

Herre's the bumper CAD model:

bumper1.jpg

and here it is in the flesh

bumper4.jpg

The Aerial guides to get the 90° between the wires

aerial right.jpg

The CAD model of the VTX tray for the back of the ZMR250 QuadCopter

vtxt1.jpg

And the VTX tray in the real world

vtxt4.jpg

Next up are some parts for my Tricopter. The items in Red are again 3D printed

On the right there is a VTX tray which also holds the LiPO voltage checker and the Loc8tor tragging tag. On the left is the FPV camera mount with built in aerial guides and servo mount to enable the FPV camera to be pitch stabilised.

vtx-camera.jpg

Next is the CAD model of my version of the Super Simple Gimbal designed by a chap who goes by the name of Crezzee on t'other forum (**LINK**

ssg1.jpg

Next up is the CAD models for an ACES II ejection seat from an A-10 Thunderbolt II.

model1.jpg

And the 3D Printed model of the seat. Shoudl have made it hollow, it was way too heavy in all it's solid glory!

And finally some scale Tornado GR4 tailpipes for a recent PSS Tornado build project.

Been out of reach of a decent 3D printer for a while now... missing it!

Thanks FBR, no limitations for your imagination then! The pilots seats look absolutely brilliant.

Wow Rez! Superb

You should make these available for the masses wink

Thanks for the comments Ian / Pete!

Pete, a few of the ZMR 250 designs are actually available on Thingiverse (**LINK**

Thanks Rez, that's really useful!

Can I be cheeky and ask if you have the files for the Tornado exhausts available to share? I understand perfectly if you don't, but they'd be great in the tail end of my new EE Lightning!

Cheers, Pete

All good stuff everyone. Here's a few from me, not so impressive but still useful:

bedadjuster.jpg

The bed on my Malyan M180 was moving during printing so I printed some retaining clips. Thaye worked but they started to wear the padding material underneath so I down loaded and printed these grips for the small adjusters. The extra grip did the jab and allow me to tighten them up properly. Bed doesn't move any more, here's a view from underneath:

bedadjuster3.jpg

My workmate look alike has been pretty handy but a pain since I broke one of the winding handles off, not a problem anymore though:

workmatehandle2newold.jpg

 

workmatehandle4fitted.jpg

Back to aeromodelling, I needed a few clevises with wider jaws for the struts on my Catalana:

Can I ask what drawing packages you are using. I have been given a Printrbot which I am running with Cura.

I was thinking about about Turbo Cad 2D/3D from Maplins, but whichever I use needs to be pretty simple for drawing 2D stuff and for trying to do 3D for the printer as I have a very simple brain and my patience is limited!

All of those prints above look incredibly sharp and accurate. How much finishing have you all done to achieve that or are they straight off the printer. Below is what I have done so far, without messing about too much with settings, but I think a bit of experimentation is the next step. I read somewhere that pla varies between different manufacturers. Is this true and where is it best to get it from?

I've on printed in ABS and it's been fairly consistent.

I use Solidworks in my day job (senior design Engineer) and use that for all my design work.

Ian101 - I haven't settled on any particular design programme but if you haven't found it already you can change the resolution in Cura by selecting the advanced print setup, there you will find the option to set the layer height (resolution of the print).

Thanks Ian and Andy.

I think I need a heated bed for ABS which I haven't got, so for the time being I will stick with PLA.

I have messed about with the layer height, but time is the problem at the moment. I bought TurboCad and am slowly finding my way around it. Again, time is the problem. Life is getting in the way.

I think this will be a long term project for me, but so far I am enjoying it.

As at the mement I work almost entirely in Depron I have been exploring ways to use lightweight printed components to work in conjunction with it.

A 'lightweight' 3 mm thick wing rib intended to replace a similar Depron rib.

Big rib

Despite its lightweight (1.9g) the printed rib is nearly 3 times the weight of the same thing in Depron but on the other hand it is considerably stronger and stiffer.

However in an all Depron sheeted wing the extra rib strength of the printed rib is not actually required so the next.step is to use Depron to 'infill' just the printed rib 'outline'. This is also much quicker to print. wink 2

Depron rib 1

Such a composite rib is now only 1.5 times the weight of the plain Depron version yet is very nearly as strong/stiff as the all printed version.

The down side is the Depron has to very accurately cut to fit exactly inside the printed outline so is relatively time consuming to do.

One by product of using this type of rib is that if used in conjunction with balsa leading and trailing edges no Depron actually touches the wing skin so a 'film' or 'tissue & dope' covering could be safely used.

Still working on it

Now that's interesting Simon, by coincidence I'm looking at wing ribs at the moment, again thinking about mixing a build with other materials. I showed some friends my first test print and they felt the internal supports were over engineered, making the rib heavier than it needs to be:

And some more. Just completed my single channel radio set with the Phil Green encoder and printed a large tapered black washer to support the aerial along with a quarter turn latch for the rear access. Once you have the printer the uses keep jumping out at you smiley

You're well into it Bob, I can design most basic things but I need to fully master the designing end of the job. There's just no limit after that.

Following on from the 20mm calibration cube, this is the first print with my Anet A8. 75mm high, not too bad for first off.20170203_165520.jpg
