Becoming familiar with openscad
I dabble in 3d printing and will download things from thingiverse.com, for example.
Some are "configurable" scad files and, to some degree, I can manage to configure them as I desire.
But, I am only "hacking", if it is not obvious from the authors comments or from what I can understand of the code, I grind to a halt.
Current project is a "knob" that I wish to use on valve actuator for the hydraulic jack on a press. It has an axial hole, round, that I would like to modify to have two "flats" and to have an additional hole at right angle to it, perhaps all the way though, to allow installation of a "set screw" to hold the knob on the jack.
Don't really expect a hand holding session, especially without posting the code, but perhaps there are some good places for me to start looking?
Thanks.
I guess the first thing is to install openscad. then click on the help
tab. look at the documentation for a while then try a simple script to
make a cube, say. Under the help tab is a cheat sheet, - click on the
cube (in the 3d section - it will open up a link to an explanation and
an example. In general, parts like knobs and brackets, can be built up
by union or difference of shapes such as cubes and cylinders.
If you want a you tube video - this will get you started

I have started two years ago with this link:
http://www.tridimake.com/2014/09/how-to-use-openscad-tricks-and-tips-to.html
It works today, I' ve chekced it.
This is a short (59 pages) introductory, some very short explanation and
the basic forms.
You can build yout first objects after 10 minutes reading. I can really
suggest it.
The tutorials are also very useful, but first I neede some really basic
knowledge...
best regards

While I started w/ OpenSCAD, I find typing and managing syntax a tedious burden, so instead do my work visually using BlockSCAD:
https://www.blockscad3d.com
once a project is done, I export it to OpenSCAD to set up for the Customizer and to add the projection() command to flatten things out to cut on a CNC.

I'm a relative novice too. After help here and much experiment (fun) I recently
printed a possibly relevant knob myself. When you've decided your design
requirement let me know if you'd like to see my code.
Meanwhile it might be helpful to see the various design options I considered for
the inner cylinder, containing the spindle hole:
#1. Simple flat plus screw hole.
#2. Flat with some flexibility, for tight fit, no screw.
#3. Improvement on #2, with bevelled top for easier insertion.
#4. Slot to hold flexible or springy metal strip (like original).
#5. Flat, solid, no screw, optimum fit via trial/error; my final choice.

Thanks for all the links. I accomplished my immediate task, and expect I will slowly become more familiar with openscad, which I find substantially easier and less frustrating to use for my needs than freecad or Solidworks. But then, I am not a “designer” by trade. Or nature perhaps.
In any event, I have unsubscribed at this email address and subscribed under one I dedicated to list use.
