Compound-Tilt Ink Bottle Corner Stand
This 84 x 84 x 42 mm stand tilts a fountain pen ink bottle 12° on each axis, about 17° overall. Ink runs into one bottom corner, so a nib can still dip in when only a few ml are left. The deck is made of open vertical fins with an L-shaped corner stop (12 mm lips), and it fits round or square bottles up to about 70 mm across with no supports and about 60 cm³ of plastic.
Two-Tier Pen Rest With Clip Trough
A 100 x 90 x 22 mm desk rest that holds three pens flat in 45° V-channels (16 mm wide at the top, so it fits anything from a thin gel pen to a fat 14 mm fountain pen or marker), with the back two channels raised on a 22 mm tier so you can see which pen is which, and an 18 x 8 mm deep trough at the front for paper clips and nibs. It gives pens a spot on the desk where they won't roll off or dry out rattling around a cup, and the channels are open at both ends so pens of any length fit; bridged tunnels in the base cut plastic while keeping enough weight that it stays put.
