Progress with wire forms

I've finished a big step in developing wire forms I wrote about in my previous post. What sounded easy turned out to be quite a challenge. The goal here was to create a wire pen holder, and this is the result: I went through close to twenty iterations. Last time I wrote about the prototyping mindset, but the message might be even simpler; just keep doing. Ruminating over ideas about how to speed up the process or trying to guess what works can kill the joy, just like any overblown project. The final form is this: The biggest aha moment...

The prototyping mindset

I used to develop new products bottom-up. I'd come up with a perfect, complicated plan, think thoroughly every phase and wouldn't move to the next one until it was perfect. I would think really hard what I wanted and what it should look like. Then I'd figure out what tools I needed to 3D print. Next, I'd sit down and model everything, 3D print, test, aaand it didn't work. So I threw it away and started all over again. Usually I went through many iterations, before I was able to simplify it enough, so that it sort of resembled what...

Challenges with wire

I work with ordinary iron wire. It's just iron burnt in an oven. It rusts naturally and has a nice black texture with mild blue and green reflections and rusty spots here and there. It often comes covered with a little oil layer to serve as protection against rust. The most prominent attribute is that it's quite tough and is a tiny flexible by keeping the inner tension. This means two things. When you bend it, the curve isn't smooth, but often "breaks" at one of the weaker points resulting in uneven bent like the one in the picture. Secondly,...

Experiments with wire forms

Recently, I've been experimenting with creating a form which acts as a guide for wire. You wrap the wire around, get it out and have a nice shape, which would take a lot of skills to create by hand. This would allow virtually everyone to create their own wire decoration with complicated shapes. My inspiration was this pot and the first idea is to create a pen holder with wires in similar curves.

Turns out AI as a guide with combination of several opensource programs (blender, inkscape, freecad, gimp) can go a...

What's new in FreeCAD 1.0.0 for a 3d printer hobbyist

This is a summary from Release notes (https://wiki.freecad.org/Release_notes_1.0). With FreeCAD 1.0.0 being released as stable, I read through the news and want to share with you what I found useful for creating models for 3d printing. I've been already using it for a bit, it's all great. Big thanks to everyone who contributed. more straightforward UIMany tools have been unified into more universal modifications which choose variants automatically based on context. It's more pleasant and faster to use. Measuring distance, lengths, angles etc. is now done by std measure (https://wiki.freecad.org/Std_Measure). It has auto mode which computes what you need based...
