Hemispherical Shell with Opposing Tabs

> Create a hollow hemispherical shell with an outer radius of 60 mm and a uniform wall thickness of 3 mm. > > The hemisphere must be exactly half of a sphere, cut at its equatorial plane. The circular open edge of the hemisphere lies in a flat horizontal base plane. > > Add two flat rectangular mounting tabs extending outward from the circular rim of the hemisphere. The two tabs must be positioned exactly opposite each other, 180 degrees apart. > > Each tab must lie completely in the same horizontal plane as the base/opening plane of the hemisphere. > > Each tab shall be 70 mm long in the radial direction, measured outward from the outer edge of the hemisphere, and 40 mm wide in the tangential direction. > > The tabs must be directly connected to the hemispherical shell and form one continuous solid body with it. > > The tabs must remain flat and must not follow the curvature of the hemisphere. > > Overall appearance: similar to a hemispherical cap with two flat baseball-cap-style visors extending in opposite directions. > > Make the geometry symmetric about both main axes. > > Create a watertight solid suitable for FDM 3D printing. > > Dimensions: > > * Hemisphere outer radius: 60 mm > * Shell thickness: 3 mm > * Number of tabs: 2 > * Tab radial length: 70 mm > * Tab width: 40 mm > * Tabs positioned: 180 degrees apart > * Tabs located in the hemisphere equatorial/base plane ### Így értelmezem a geometriát Felülnézetben nagyjából: 40 mm ┌────────┐ │ │ │ 70mm │ │ │ ────┘ └──── ╭──────╮ ╭──────────╮ │ Ø120 │ ╰──────────╯ ────┐ ┌──── │ │ │ 70mm │ │ │ └────────┘ 40 mm Oldalnézetben pedig: ● ╭───────╮ ╭─────────────╮ ╭─────────────────╮ ───────┴───────────────────┴─────── fül Ø120 fül alapsík ``` Van azonban egy **fontos méret**, amit még érdemes meghatározni: a **héj és a fülek vastagsága**. Én most 3 mm-rel írtam meg. Mechanikailag terhelhető nyomtatott alkatrésznél lehet célszerűbb például **4–5 mm-es héj**, illetve a fülek akár ennél is vastagabbak. Ha megadod a **héjvastagságot, a fülek vastagságát, és hogy lesz-e a füleken furat**, megírom a végleges, méretpontos TextoCAD promptot.
