Gazelle Esprit Comfort bicycle rear wheel adjustment screw holder

My bicycle's rear wheel adjustment screws are held in place by these small plastic holders, however they tend to crack when the plastic gets brittle. After one of them broke, I re-created them in Solidworks and printed them as a replacement. Should fit right in, since the dimensions are basically the same, with the only difference being that the open space in the corner is now 100% filled in in hopes of increasing it's strength.

They might fit other Gazelle bicycles (or maybe even other brands) as well, but I only tested it with my own bicycle so I can't confirm which other bicycles it does/doesn't work for.
