Yes - using POE for power and data crossed my mind! But ultimately I ended up only towing fishing line which I then used to pull the cable, which was probably easier than directly towing shielded cat 6!

I unimaginatively called it Duct Rover 9000 but I like that, or Mclane :D

that’s great information - thanks!

How long depends on your humidity. If you live somewhere with high humidity, PLA or PETG filament can go bad in a couple of weeks or less. In a dry location, maybe never for PLA. Nylon will go bad anywhere in a matter of hours. It’s not easy to tell if filament is wet - weighing filament can tell you about the moisture gain/loss, but of course doesn’t work when you are actively consuming it. When filament gets wet, prints start to get bad in various vague ways that can seem like printer tuning issues. Sometimes it’s bad bed adhesion, sometimes poor first layer quality, stringing, or bad overall print quality.

If you want a good storage solution you need an airtight box. I use Iris Weathertight storage boxes with 1lb desiccant canisters and a humidity monitor. The 62qt box can fit 16 spools and room for the desiccant.

Dude, awesome post! In the last couple of weeks I too have switched to FreeCAD. The real turning point for me was finding RealThunder’s fork which is infinitely more usable than the main fork due to stable geometry. At first I wasn’t so sure I could hack it, but in recent days I’ve been getting really comfortable. I haven’t opened Fusion in weeks for anything but to grab measurements from my old designs! Cheers.
