Placeable Blaze Rods (Legacy Fabric)
This minimalist mod transforms blaze rods into full decorative blocks that can be placed in the world. Similar to end rods, they emit light and can be oriented in different directions.
Requires the library mod Collective (Fabric) and Fabric API.
The block design is based on end rods but uses the color palette of blaze rods. The blocks emit light and have directional orientation:

It's important to note that blaze rods retain all their normal functions - they can still be transformed into blaze powder for crafting and other purposes.
This is the version for Fabric 1.16 and 1.17. For newer Fabric versions (1.18+) and Forge, updates are available on the main project page.
