3D printing looks great :)

Just wondering what is the purpose of the component in a window.

It's to block the external darkening shutter (not the windows, the external, in Italy it's named "Persiana"). The original it's iron, but I've created the same, with a better shape and pretty solid (100% infill of course), in very basic PLA :-)

This was my first time ever using Part Design, very cool and fun!

Iron block system for my darkening shutter (outside the window) is broken. Easy redraw from scratch in Part Design with @FreeCADNews
and then printed. Thanks #FreeCad #opensource #community #foss :-)
Looks good. I was just looking for something similar for my back door. What to print it on my Creality Ender 3. The model looks pretty simple.

Here you have my project file, if you want to modify it, very very simple Part Design job :-)

Great project: modeled, printed, done.
Some comments:
- I would have made all sketches fully constrained, because I usually have to readjust things after a first prototype.
- Choosing the origin so that you can benefit from symmetry, even modeling only half and doing a mirror is possible.
- Using the Hole feature saves one feature/dressup and makes you less dependent on topology.
- The simple copy seems superflous to me.

Thanks Chris :-)

1) That's right. It was fully constrained for the 3/4 of the time, but at the end I made some (big) modification from scratch, so the final body and sketches were not so clean.

2) Mirroring was the first choice but I was not so capable (now I am :-)), I made a lot of other models design to finish this little micro project. In the beginning I used Part creating only boolean edit, it was very difficult. I never used Part Design logic, so this was my first time, it was fun, but I had problem understanding part design flow process, and that part it's not so compatibile with part design feature design. I can say that this micro-project was very useful to understand :-)

3) I've seen this, because when I made some modification, a lot messed up quickly becuase this wasn't created with discipline. So when I was sure about measures, I quickly recreated all from scratch (we can say "rought").

4) simple copy was to experiment with rendering in mesh and to export, i've not saved that.

Thanks a lot for your suggestions :-)

Updated this microproject with mirror feature and fully constrained sketches :-)

Thanks a lot to all for advices and suggestions ;-)

I just grinded a 120 grad spotting drill, using FreeCAD as help tool to figure out the angle needed to set on the grinder. Wonky geometry, but the drill bit works ;)
