"Electric torch", a happy accident, as Bob Ross would call it. Illuminated industrial chimney at the Landschaftspark Nord, Duisburg/Germany. No PS, just long exposure and shaky hands.

Diving into photogrammetry. Took 50 shots of this

Diving into photogrammetry. Took 50 shots of this little fella (unfortunately not Sonic the Hedgehog) from different perspectives and processed them in COLMAP and MeshLab (both OpenSource/free). An easy way to get access to 3d-scanning.

Compared to the effort the result is quite impressive. I didn't expect the complex surface of the fabric to be processed properly, but it turned out well. The final mesh consist of ~1.000.000 vertices and ~2.000.000 triangles. No further post processing done.

The mesh is almost ready for 3d-printing, it only needs to be closed on the bottom and the number of polygons should be reduced a little bit. It might actually be a good idea to automate the scanning process with a turntable.

Rendered in Blender/Cycles.

C/2020 F3 (NEOWISE)

Next iteration of comet photography (gear upgrade, Canon EOS RP):
_ wide shot (40 mm, F/5, 13 secs., ISO 1600)
_ close up (105 mm, F/5.6, 2.5 secs., ISO 12800, stack of 7 images)

Made some adjustments to curves & contrast in PS, no noise reduction.

Voronoi coaster

https://www.thingiverse.com/thing:4545744

A simple coaster (d~100mm) made from the notorious voronoi-pattern. The pattern helps with flexibilty, so cups or glasses won't wobble. Modelled as a demonstrator for flex-materials (Grasshopper/Rhino).

Flex-materials work best. Bear in mind that using this with hot cups may leave an imprint.

Rendered in Blender/Cycles.

C/2020 F3 (NEOWISE)

Ok, this was just a quick'n dirty shot from the hip through the window of my bedroom (with my old Nikon D50, 20 secs., F/5.6, 50 mm). There's still a lot potential for improvement...

LCD Display Mount for Creality CR-10 www.thingi

LCD Display Mount for Creality CR-10

www.thingiverse.com/thing:4540970

This display mount attaches directly to the 2020 extrusion profiles of the Creality CR-10. It holds the usual 12864-type LCD, if you want to convert the classic CR-10 into a boxless version.

Parts needed:

- 4x M3x10 hex socket screw
- 4x M3 T-Slot nut for 2020 extrusion profiles
- 4x M3x8 hex socket screw (you can use the original mounting screws)
- 4x M3x4x5 threaded inserts (use of a soldering iron required)

Use a soldering iron (~200 °C) to press the threaded inserts into the back of the mount.

It is recommended to mount the holder first to the extrusion profiles in the front of the CR-10 and add the display afterwards (the screws are much easier to reach this way).
