The new Modular, 10255 Assembly Square, is available today and a LEGO® piece that it contains has been analysed by Gary Davis (
Bricks for Brains).
It's not a euphemism, an insult or a new action hero.
Ballshaft is the name I'm using for a relatively new element officially known as 3.2 Shaft W/5.9 Ball and, on BrickLink, Bar1L with Towbar (Design ID 22484). The ballshaft was introduced
early in 2016 in the Nexo Knights range. It was first produced in Transparent Fluorescent Reddish Orange [TLG]/Trans-Neon Orange [BL] (Element ID 6131711) in four sets, and in Transparent Bright Green (Element ID 6139234) in one set. Now the Transparent Bright Green version is available in a second set,
10255 Assembly Square.
It is also available in Dark Stone Grey [TLG]/Dark Bluish Gray [BL] (Element ID 6158469)—a much more useful colour for MOC builders like me. So I was delighted when New Elementary sent me a small batch of dark grey ballshafts to play with. With shafts inserted, the exposed balls can be used represent various things, such as elements of a hairbrush.
