The solution to spare keys, and attaching any number of things to any number of other things, is the ubiquitous split ring. These are the even ubiquitouser 15/16" OD x 1/8" steel ones. And at this price you could buy enough to string together to make a steel curtain and add a little snazz to your pad.
These are the split rings with the beveled profile, the good ones. The bevel and the largeness of these rings translate to fewer chipped fingernails and blurted-out obscenities. Measure 1-1/2" dia x 1/8" thick, in steel, and hold a bunch of keys.
This float valve assembly has a 2-15/16" x 1-9/16" dia white, barrel-shaped plastic float on a 1" x 1-1/4" stainless steel arm, making it look like a float valve for a Lilliputian toilet tank. Arm is connected to a 1/4" ID check valve with a 1" long flattened shaft and cotter pin connector. Designed for a bottom mount.

Hardware from Monkey Grip, Inc.? Those would be professional–quality
tire repair products –– in this case, air–line couplers with a 1/4 NPT
thread on one end and a fitting for a T–type connector on the other. The
1–1/2” long interchangeable steel nipples have T–connectors that are
threaded. Excellent quality, whatever your application.
The world of surplus works in mysterious ways. Here we have assorted V-shaped aluminum channels 5-3/4" long x 5/8" wide across the 120° Vs. Picture these nestled behind glass thermometer tubes, imprinted with assorted scales, each with a small mounting hole at the top, maybe tiny crimp-clips to mount the thermometer that isn't there, and a diamond-shaped opening at the bottom for the glass bulb that also isn't there. Then add your own thermometers, use them as teaching aids, string 'em together for tracks or marble runs, or get really creative.
Black plastic vented grilles with (19) round holes measure 2-1/8" OD x 3/8" thick with (4) snap clips to hold them in place. Originally for stereo speakers, they were designed to fit into a 2" dia port.
