60 mm Desk Grommet Pen Well With Cable Chimney
A pen well that drops into a standard 60 mm desk grommet hole. Lift out the stock grommet cap and press this in: it holds pens in the 72 mm-wide, six-cell ring, and a central 22 mm chimney still lets a charging cable come up through the desk. A 58.6 mm spigot with eight crush ribs (60.6 mm across the ribs) grips the hole, and a 45° conical seat centres on the hole edge. The spigot reaches about 16 mm down, so it suits desktops 16 mm or thicker.
60 mm Desk Grommet Cable Port
A drop-in cable grommet for the standard 60 mm (2-3/8 in) desk grommet hole: 76 mm flange, 22 mm deep barrel with a Ø52 mm bore, and a 16 mm side slot so a cable with a moulded USB or barrel plug lays in from the side instead of being threaded through. Six compression ribs grip holes from about 59.5 to 61 mm with a 45 degree lead-in taper, and two 3.4 mm M3 clearance holes let you screw it down on thin laminate tops.
