they’re called trees. I like them too, makes the print look organic-grown.

Is your bamboo setup with 4 spools? Did you print the supports in water soluble material? I know purging of the nozzle between spools slows down the print process tremendously.
No, only white PETG for model and tree support, otherwise it would last many hours longer.
(Edit: I’ve tried in the slicer, with two materials (separate support) the printing time would increase to approx. 1 day and 22 hours.)

I hope you installed some rubber washers or a metal frame and spacer bolted on both sides between the holder and the wood, because wind will twist the wooden top over time, which eventually cause the holder to crack and break. I know from experience

Thanks for the tip, I’ll keep a close eye on it.
The water barrel in the centre will also serve as a bar table for a beer in between or for transplanting small plants. Thanks to the 3D printed adapters (TPU) that are glued to it, a suitable table top can now be placed on top easily and securely…

That should be impossible given that it’s all triangles..
Or am I missing something?
We looked for a suitable place for a tray and found one in the storeroom with the help of two printed holders…

Large facets (few triangles) compared to more triangles or a sphere, the airflow is disrupted at the edges of the segments, likely possible causing turbulence.
It gives higher aerodynamic drag compared to a smooth sphere and an increased drag coefficient.
Also an increased vortex formation behind the object, especially at higher wind speeds which creates a vacuum and disform the ‘sphere’ back side
Localized pressure peaks on the facets oriented perpendicular to the wind direction and also disform the ‘sphere’ front side of the wind direction. So the top wil be a pivot point and may get twisted a little, maybe enough of to crack the plastic.

The plant labelling should be used again, but if they are all mixed up in a box, you can’t find the one you want. Now they are sorted alphabetically…

Good idea. I always end up losing them or keep them all into one big, messy shoebox.

For the greenhouse door, a thick magnet should hold the door shut. I embedded a metal plate (diameter 65mm) in the 3D-printed handle during the printing process. A round rubber-coated magnet is screwed onto the opposite side.

A magnet is also installed so that the greenhouse door can be opened in good weather. Embedding the relatively large metal plate only worked after several attempts. In the end, I coated the plate with hairspray and placed it on the printing plate to heat it up from the start, after which the large surface could be easily overprinted.

Thank you! I don’t remember the filament exactly, but from the color I would guess it was PLA. The iron is stored only when cold, so it’s fine until today.
Thank you for your reply.
The rain ran behind the new door and into the interior of the Geodome. Now the slit is covered and the water runs off outside.

Good solution. Do you have any sort of concept of how long your 3D printed parts will last with UV exposure? I made a couple of brackets to mount a rain gauge onto a post on our deck railing but I wonder how long until they fail. They are cheap enough to remake if it comes to it.
This inlet for the pool from 2020 has been outside continuously since installation (even in winter, exposed to UV rays and regular contact with pool chemicals) and is still holding up. As long as the temperature does not exceed the point where the material softens, in my experience everything lasts longer than expected.
That’s good news. I hope it doesn’t get hot enough here for my brackets to soften. I guess if it does, the rain gauge might also melt.

I did a similar bracket out of PLA years ago. It did not survive one year. The replacement is made of ABS, and it is several years old.
