Re: Coil forms, Q, and instruments


Jim,  I had the original hobbyist version and Autodesk said my "free trial" was over !

I tried to sign up again for hobbyist license and couldn't find a means to do it.

Points would be appreciated.

In the mean time, I am getting better at using FreeCad.

Suggest you check again, Fusion 360 is still free for personal/non commercial use.  I have been using F360 for 3 years now, legally licensed for personal use and have not had to pay a penny for it.

FreeCad is not as intuitive as AutoDesk Fusion 360, but I am unwilling to pay their exorbitant price for hobby use.

I have been designing things with FreeCad [on and off] for several months and becoming more comfortable using, not proficient, but very comfortable.

It does have a few quirks (bugs) you will discover along the way but nothing you won't find a work around for.

It is a bargain at 2 or 3 times the price !

Hello Jim. Very nice work on the coil form. I test printed your .stl file and it came out perfectly.

If you don't mind my asking which CAD application do you use?  Some time ago I attempted a similar project in FreeCAD. However, I encountered difficulties and set it aside.

Hi David,

Here's the STL file, attached, and a photo.
It's such a thin tube it needs a "brim" for buildplate adhesion

There's a tiny hole at each end to pass the wire through to secure the turns.
I plan to make another with multiple holes to accommodate different turn counts.
