Space Widener[]
A curious item from 1920, it actually increases spaces by extending to a full 6 feet. If used in a closet 4 feet wide, the closet will expand by another 2 feet. sadly if removed or reversed, the space will compact to its' original size, possibly damaging items stored in the space, or causing them to move into space available (ie up and out)
Very rare to find one in working condition. But they can be repaired at Crafts + Dex + equipment (15-20 success) extended every roll equals 30 minutes spent on attempting to repair. If a main part is missing or severely damaged such as the magnets, motor, or pistons, they cannot be replaced, as they were built special for the product.
Now, if you could find the original creator....
(storyteller determines the severity of the damage, age, malfunction, and thus how many successes are needed to repair)
