A Better Fan Shroud I already updated my 3D Printer fan shroud a couple of months ago. It should cool the filament more effectively and evenly. I think it did a good job. Unfortunately, the shroud got too hot several times and was deformed. I was afraid that it now had reduced cooling performance. I found an update to the fan shroud that looked very efficient, and somebody analyzed the airflow, and it appeared to be very effective in cooling the filament.

Well, Crap, what a waste of time One would guess that I should have known better with the work experience I accumulated in the software engineering field. But, it’s Friday evening, after our social team meeting, and I am still excited to finish something substantial for this feature that I’m working. Lots of moving parts, refactored code, loose ends, and hastily glued together code without any safety net. A couple of new unit tests for the new feature and some legacy code that I have to touch.

Designing a Spacer for my AxiDraw Plotter I have an AxiDraw V3/A3 Penplotter that I bought to satisfy a desire to own such a fantastic machine. It started in my teen years working with HP Plotters in our university lab at the TUHH. I could not afford an HP Plotter back in the day, so that desire was never satisfied. Jumping forward to today: I bought the AxiDraw Plotter in the Summer of 2021, and I ordered the Magnetic Easel.
