Fume extraction

Despite deliberately having an extract fan through the wall above the area that I have my 3D printers, the smell of isopropyl alcohol (IPA) persists for longer than I would like after I have finished cleaning up resin prints.

To try to reduce that, I have designed and built an extraction hood that I can position directly over the source of the IPA.

It's based on a long wall mounted monitor arm and 100mm (4") flexible ducting. Both ends and the hose clamp are printed.

I do not know yet if it will resolve the issue, but I am pleased with how it has all gone together. It folds out of the way and I can position it to where I want.

Bits in the garage

I made a couple of minor changes in the garage to make things more convenient.

I added a bike maintenance stand to the exiting bike rack. The clamp was the one I used in my old shed, up to a couple of years ago. 

It fitted in the key clamp tubing and I added an interlocking joint so that it holds in two positions. One for use and one out of the way. The idea came about last weekend because I had a quick task to do that was more convenient on a stand, but setting up the portable stand took almost as long as doing the job.

This arrangement makes quick jobs that little bit easier.

The other bit of tidying up I did was to add a vertical rack for long lengths of steel bar.

I would have preferred a horizontal rack, but that would be harder to fit in.
