To ensure that the dome can cope with a few hot days in summer without manual watering, I am preparing an automatic irrigation system. Of course, this requires a lot of 3D-printed brackets for the numerous hoses…
To make it easier to open the door of my geodesic dome from the inside, I have also attached a handle to that side so that the resistance of the magnet can be overcome more easily.
A drawer in the caravan opened while driving, caused by a broken bracket for the lock. There were a number of air pockets in the injection-moulded part, it’s a miracle that it lasted so long.
Your clear tube with water - you said you’re using it as a fill guage for the barrel to which it’s attached. Slightly worried it won’t work as you expect because of the cap at the end of the tube.
Water leveling requires equal AIR pressure above each end. And your cap would cause the air inside to compress if the barrel water level rises! Solution: Make sure the top of the tube is vented somehow!
Missed that! I beg not enough caffeine - my eyes were attracted by the picture of the installed cap - and didn’t register the model of the cap above it!
The holes are actually quite small, but the airflow is also very low, as the liquid level changes only slowly. Thanks for the tip, though – better to be safe than sorry.
At first, I tried using strong double-sided adhesive tape, but unfortunately that only lasted a few days. I then printed a second version with a hole for a countersunk screw; luckily, this was able to use a hole in the old mount that was no longer in use, so I didn’t have to drill a new one.
The tap has two connections, so I can only turn on the hose for the level indicator when I want to check the level; the rest of the time, the hose could fall off without any water running out of the barrel – it’s a small safety feature.
A new CO detector in the caravan needed a place to go without having to drill into the wall. Printed in PLA with a support structure in PETG – a neat solution for a nice overhanging surface…
