3D treats

Ear for coil

Do you have a 3D printer?

[Op04]

A bit bulky and too much metal.

The metals shall be removed, exchange with nylon bolt n nuts. Alternative for ears, can applied before pouring resin.

No, I don’t have. I put here coz it related.

If you would like, I can send you a printed clevis which is designed to take a Minelab shaft connector.

Hi MartinB,
Thank you for your help, but I have to refuse because I can make it here easily even though I have to hire a 3D printing service. Besides, I live in SEA, the fare is decent. So thank you ...

No problem. Always here to help

I can't seem to find a 3D model for collapsible pipes, if anyone has anything I would be extremely thankful.

Hi
My filament supplier has advised me that 3D printed stems are unlikely to be strong enough.
You will be better off using carbon fibre tubes which are stronger and lighter.

[MDfanatic]

Depends on the print orientation, if you print it horizontally it will be strong enough but the supports might be a pain to remove.

You could always try a square section tube then you only need to worry about internal supports. If, like me, you only have a small bed, then you will have to print quite a few sections and glue them together

Concentric Coil Experiment from ITMD

Page 134 of ITMD gives a really nice example of an 8" concentric coil design so I thought I'd have a bash at doing a 3D print of a suitable former.



If anyone is interested I can post the .stl file or the Freecad design file

The stl would be handy thanks.

Concentric STL

Here is the STL, it's probably a good idea to use supports when slicing.

Please could you also post the FCStd file for FreeCAD?
When I load the stl file in Repetier Host, it says that the model is non-manifold (i.e. it's not watertight) which may cause a problem during slicing.

Concentric Freecad file

No worries.
There is a spreadsheet within the Freecad design which has the adjustable parameters if you want to tweak it.
I use quite a small grommet so you may want to enlarge the hole.
This is about the biggest I can get on my Ender 3 printer..

Thanks.
I've never used the spreadsheet option in FreeCAD, so now I need to go and read the manual.
