Followed along, and made a fender for my bike.

A vent cover for my 3D printer that will hold an iphone on the outside of the printer, so that prints can be monitored via the web (with manything app). I wanted the design so that the phone could be dropped in, and a spot for the plug to fit through, so the phone could be plugged in to charge. After modelling it, I realized that some thought needs to be done right from the start how it will print. I either need to do some mad supports, or print the part in two pieces, and glue together after (will likely do this).

Hey there, For H2, make sure it's cleaning vinegar/mg. Normal vinegar will work, but it's slower (lower concentration). For O2, Age of yeast/H2O2 matters. The H2O2 degrades to water over time. The yeast I always use the single package stuff, because I found the jar once opened didn't work as well for very long. Also, make sure there is a small amount of water in the bottom for propellant. And when transferring from one collection chamber to another, you have to be careful not to squeeze any water out, because this will let room air in, which will alter your ratios. Also check your seeing a small spark between the jumper cables to make sure the piezo is working properly. Hope these suggestions help. Hopefully, you're having fun. This took many years of fiddling to perfect it/to ge…

This took many years of fiddling to perfect it/to get it to work LOL. I use to use full-size water bottles in the foyer of our school. Then I was scared I would cause an emergency lockdown at some point. Was never brave enough to try a water cooler bottle :)
