PSA: Star-shaped Bowden tubes are terrible for flexible filaments. Instead of reducing friction, they can increase it—because the filament gets pushed into the star “corners” under tension.

It took a few goes, but this is a reasonable representation of the clip profile made via rubber stamp technology. It's good enough to clean up and get something actually good.

Gonna scan this with a clear background, clean it up, then use one of those picture-to-3D-print variable-density backlight image panels to make it an object, and then extrude it up from the profile until it's the right size.

A white piece of paper with some faint impressions, a green stamp inker, and the impression made by the side of the broken but glued back together clip, in green. It's fuzzy, but not in a way that it can't be cleaned up.

Here's a really cool text effect I made on @codepen: individual letter rotation + extrusion https://codepen.io/thebabydino/pen/WNqvdmN

No text duplication, no splitting the text into individual letters, no funky fonts.

Just #SVG #filter magic! 🪄

Screenshot. Shows the text "create" in all caps. Each letter has its own random rotation, a transparency outline and a multicoloured neon extrusion. There's also a subtle shine effect across the whole thing.

No text duplication, no images save for CSS gradients, no part of the effect baked into the font, no JS. It's all clever #CSS and #SVG #filter magic! 🪄✨

No text duplication whatsoever, no long shadow list, no funky fonts, no JS, no images other than CSS gradients. Extrusion is all #SVG #filter magic 🪄✨ - as illustrated by the recording below including the DevTools panel.

#svgFilter #textEffects #textEffect #extrude #extrusion #code #coding #frontend #CSS #web #dev #webDev #webDevelopment #cssGradient

#3D text with double outlines & inner shadows. Absolutely no text duplication whatsoever needed, not in the markup, not in pseudo content. No funky fonts. Contenteditable with no JS needed.

Can you figure out how before checking my code?

Here at Camp Persuasion
where the ends
always justifies the means
the go to method
of loyalty indoctrination
is the tried and true
fingernail #extrusion

So when they drag
your subversive carcass
to the Charlie Kirk room
best bend the knee immediately
and get with the program

#vss365 #poetry #poem

Here at our collective
point of inflection
we can commence the #extrusion
of the beasts now entrenched
that were spawned by our neglect

Purging these rogue elements
will be a long and painful process
but it needs to begin now
before none of us
who still give a damn are left
to resist

Oh no, Openbuilds goes out of business 😓

The CEO Mark Carew invented the V-Slot extrusion in 2013. We use them on the Bear because the V shape offered an easy alignment during the assembly and more flexibility for the printed parts (no support needed).

Everything must go, check them out:

Thank you Openbuilds and the community for those 12 years 🙏❤️

This sketch shows the arrangement of #dentils in the classic variation of the #IonicEntablature. It shows the full layout, but most of the top is obscured by the top portion of the #cornice. Only the outside square shapes are actually visible.

Each #dentil has a square "footprint" that is 4 parts by 4 parts (32*32 units) and is 6 parts (48 units) tall. The spacing between each dentil is 2 parts (16 units).

Dentils project 4 parts (or 32 units) from the face of the #fascia on which they rest.

Each face of the fascia has 7 dentils with the middle dentil laterally centered and directly in front of the column axis. The 2 side dentils are on side faces, and that is apparent in the darker shading in the sketch at https://pixelfed.social/i/web/post/790782316675150160. Take the time to reconcile this with the numbers listed in #Scarlata's #PracticalArchitecture.

The 3D reconstruction from the #primaryProfileCurves is very similar to that of the #IonicPedestal, with #extrusion, #mitering, #joining, and #capping planar holes as described in https://pixelfed.social/i/web/post/790645054230337543 — just set the dentils aside, for now.

Once you have capped the #planarHoles to get a solid, analyze the edges of the solid in the #CAD program for #nakedEdges and #nonManifoldEdges.

Then, extrude the dentils outline (in the top view) to a height of 48 units (in the front view).

Now perform a #booleanUnion of the two solid shapes to get the complete #entablature.

Finally, check the edges of the solid in the #CAD program AGAIN for #nakedEdges and #nonManifoldEdges.

With this, we have finished two of the three main components of the #IonicOrder. There's a modern version of the Ionic entablature with #modillions, which I will describe later.

Next, we move on to the biggest, most conspicuous part of the order — the #IonicColumn.

Here is how extrusions are made:

As you can see it's not a super accurate process. This is why it's not recommended to screw on linear rails and why some companies offer a machining service to make a flat surface. Another common practice is to let customers discover over-wrapped/twisted extrusions and then help via support.

No text duplication, no JS, no images save for CSS gradients, no long lists of values for anything (like text-shadow).

Just plain text + CSS gradients + blending + the magic of #SVG filters for extrusion + texture 🪄✨

The text "Dusty" in thick cursive. Each letter face has a top to bottom grainy gradient from lighter to darker blue. This has a discrete inner shadow and casts a shadow on top of its white outline. The whole thing is extruded, with the extrusion having a grainy mesh gradient. Top to bottom goes from gold to crimson, while also getting progressively darker as it goes further from letter face. The entire extruded assembly casts a diffuse shadow on top of a textured, top middle lighted, 3D striped bluish background.

No text duplication single div 3D + stroke effects (double stroke, gradient stroke or stroke with shadow) - it's all in the magic 🪄 of SVG filters!

Screenshot. Shows the text "now" in all caps, with a light blue to bluish green top to bottom gradient letter face, a double stroke and a 3D extrusion effect. The outer stroke is white, while the inner one is a top to bottom gradient one from a medium blue to the same green as the letter face now, effectively looking as if it's disappearing into the letter fill at the bottom. The extrusion is deeppink at the bottom and a gold to orange top to bottom gradient on the right side.

The page background is an aqua to deep blue dithered gradient.

DevTools open on the right side to highlight the fact that there's no JS, no text duplication whatsoever, not in the markup and not in any pseudo-element content.

Screenshot. Shows the text "meet me halfway" in all caps on top of a blue-tinted image of stairs in the forest. The letter face has a hashed background - dark orange hashes on top of orange. The text also has a thin white outline with sharp corners, as well as an inner shadow and two 3D extrusions/ long shadows towards the bottom right, the first one a solid sea blue and the second a semi-transparent one.

Screenshot. The text "Beautiful" in a fancy, cursive font. The text face has a lighter to a darker pink gradient and so does the thin text stroke, which also has an inner shadow. There's a darker pink lateral 3D extrusion effect and a dark pink shadow being cast by the entire 3D text.

Screenshot. Shows the text "chocolate - and - butterflies" in all caps split across 3 lines on top of a bright teal background with subtle semitransparent black hashes. This text is skewed such that its top right corner is pulled up. It has a purplish grey extrusion which has just a white outline at the top (the letter fill is transparent there, allowing us to see through to the base) and a hashed letter fill (white and light violet hashes) at the bottom. This in turn has a smaller purple extrusion, half the size of the first one, as well as a third semitransparent black extrusion, the same size as the first (grey) one.

This is semi-solid aluminum 3D printing! Unfortunately, according to Ric Fulop (CEO and co-founder of DesktopMetal), it can't be commercialized because the temperature control is very difficult and, when it fails, is very problematic. Nevertheless, it's an impressive demonstration.
