This module allows you to craft custom items using a special crafting table. Recipes are added by other Gamemode 4 Modules.



A Custom Crafter enables other Gamemode 4 modules to add custom recipes, and supports multi-crafting and item nbt - unlike Minecraft's recipe system. Alone, this module adds no recipes. It can be used to add new items to the game without having to replace an existing one.

An example of a module adding recipes is Standard Crafting which adds recipes for horse armor and cobwebs, among other items. Another example is the Heart Canisters module, which adds a custom item that increases player health. The canisters themselves are textured player heads, which requires specific item nbt. See the Expansions section below for more modules that add recipes.

Multi-crafting is also supported by Custom Crafters, allowing multiple items to be crafted at the same time. This works as long as each non-empty slot has the same number of items and the resulting output does not exceed one stack.

A Custom Crafter can be disabled by powering the dropper with redstone.


To create a Custom Crafter, put the recipe of a dropper inside a dropper, and throw a crafting table on top of it. When broken, a Custom Crafter will drop the items that was used to create it.


Three step creation of a custom crafter


Custom Crafters can be moved with Relocators. When placing a relocated Custom Crafter, the dropper will face away from the block that it was placed on.

Technical Details

Recipes in the Custom Crafter are processed every 0.8 seconds, 16 game ticks, or 8 redstone ticks.

If the stack size for crafting multiple items would result in an output with more than the resulting item stack would allow, the crafting recipe will not initiate. e.g. if a stone recipe would yield over 64 stone (due to multi-crafting), the recipe would not work. Another example is if a snowball recipe would yield over 16 snowballs.

Custom Crafters do not process recipes when empty or powered; leaving a Crafter empty is an excellent way to help reduce strain on the server.

Expansion Packs & Reliant Modules

The Custom Crafters module doesn't do anything on its own. Expansion packs for this module add custom crafting recipes to the game. Some reliant modules depend on this module in order to properly function, for example to craft some items.

Previous Versions

MC 1.8 Versions

The MC 1.8 Versions a Custom Crafter would only drop the crafting table upon breaking it; the 7 Cobblestone and 1 Redstone Dust used to craft it would be lost.

MC 1.9-1.12 Versions

Prior to 1.13, items in slots that should be empty would be ignored, causing the possibility of losing items. Additionally, Multi-Crafting was not available, so items could only be crafted in sets of 1.
