MCToolHub Sphere Generator review
A free web tool for sphere, dome, and shell blueprints with counts and coordinates.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
For Minecraft builders planning spheres, domes, or shells, MCToolHub Sphere Generator turns a chosen diameter into a block-by-block blueprint. It supports hollow outer-shell and filled forms, with diameter presets or custom input and a choice of blueprint material and block ID. The web tool is aimed at solo and small-scale building workflows where knowing the layout and material totals matters before placing blocks. It is free, and the vendor says generation runs locally in the browser without an account. The page describes compatibility with modern Java Edition building workflows.
The main strength is how the generator makes the shape inspectable rather than presenting only a finished image. A rotatable, zoomable 3D preview can be navigated horizontally by layer, and each layer displays its block count. The interface also shows total block and material counts, useful for estimating requirements for a build. Users can copy all 3D coordinates or download a PNG snapshot of the current view. This makes it a practical choice when a builder wants both a visual reference and position data; it is less suited to someone looking for a general-purpose generator across many unrelated Minecraft structures.
Its scope is deliberately narrow: the shape library centers on spheres, domes, and shells. The available export options are 3D coordinates and a PNG snapshot, so buyers who need other file formats or broader shape coverage should look elsewhere. A 500-block quick-diameter preset is shown, but it should be treated as a preset rather than an established maximum. MCToolHub lists email as a support channel. Pick this tool when the task is a spherical build and layer-level counts or coordinates are useful; choose an alternative for a wider shape library or different export needs.
