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.
Bolt-Through Tarp Grommet Repair Patch
This patch replaces a torn tarp, pool cover, awning or shade-sail grommet without a grommet-setting tool. Print two identical 56 mm discs, put one on each side of the fabric and bolt them together with four M4 x 16 mm screws. The 12 mm centre eye takes rope, bungee hooks or tent stakes. Each disc has 4.5 mm clearance holes on a 36 mm bolt circle, a hex pocket that holds either an M4 nut (7 mm across flats) or the screw head, and two raised ridges that grip the fabric. The outer edge is chamfered so it won't saw through the tarp.
22 mm Snap-In Step-Down Cable Grommet
A snap-in grommet for a 22 mm hole (the common step-drill size) in a project box, dash or panel wall up to 3 mm thick. It has a 36 mm flange, four barbed spring fingers and a knock-out membrane with score rings at 4, 7, 10 and 13 mm. Trim to the ring that matches your cable and you get a snug pass-through, not a loose hole.
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.
