Spawner Base – Bone to Bone Block Converter

This build is a fully automated Spawner Base designed to process large amounts of bones and convert them into bone blocks, which are then automatically stored in shulker boxes.


The system works as follows:

Bones obtained from a mob spawner are fed into the input system, where they are automatically crafted into bone meal and then further crafted into bone blocks using a redstone-controlled auto-crafting setup. The finished bone blocks are transported through a hopper and water/ice-based item system into a shulker box loader, allowing for compact, long-term storage.


The base features a dual-module layout, enabling high throughput and continuous operation. Thanks to synchronized redstone timing with observers, pistons, and comparators, the system runs reliably without item loss or clogging.


Key features:

Fully automatic bone → bone block conversion

Integrated shulker box loader

AFK-friendly design

High efficiency and stable redstone timing

Compact and expandable modular structure

Optimized item transport using hoppers and ice/water streams

The entire mechanism is enclosed in a protective casing to prevent interference and improve performance. This spawner base is ideal for players who want a hands-free, scalable bone block production system for large survival worlds.
