How to set up Fabric 3D Shareware v1.34

Install Java 8 or newer (e.g. Eclipse Temurin) and check it with java -version.
Download the Fabric server launcher above (about 178 KB) into an empty folder.
Start it with the script below. On the first start the launcher downloads the vanilla 3D Shareware v1.34 server from Mojang and the Fabric libraries — this needs internet access.
Accept Mojang's EULA in eula.txt (eula=true) and start again.
Put mods into mods/.

FAQ

What Java version does Fabric 3D Shareware v1.34 need?

Fabric 3D Shareware v1.34 needs Java 8 or newer. Running it on an older Java fails with an UnsupportedClassVersionError mentioning class file version 52.0.

Is Fabric 3D Shareware v1.34 safe for my survival world?

Only on a copy. Preview versions are experimental and upgrade worlds irreversibly; keep a backup and don't switch a live world to a snapshot, pre-release or release candidate.

Why is the Fabric server file so small?

It is only a launcher. On the first start it downloads the vanilla Minecraft 3D Shareware v1.34 server from Mojang and the Fabric Loader libraries.
