Minecraft circle, portal and beacon planners
A little help. A little more fun. First product: a circular wall you can actually finish. Diameter and height in, stacks and the current row out. Phone in one hand, pickaxe in the other.
Circle tower planner
Hollow ring or filled disc, wall height, materials, and a row you can mark done without losing your place.
Circle & oval generator
Hollow rings, filled discs, and per-row block counts for towers, arenas, and farms.
Nether portal linker
Convert Overworld ↔ Nether coordinates with Java floor division and search-radius notes.
Beacon pyramid calculator
Tier 1–4 materials, stacks, effect radius, and shared bases for 4 or 6 beacons.
Who this is for
You already know what you want to build. You do not want a wiki tab, a spreadsheet, and a Discord screenshot open at the same time. If one page saves you a miscount or a ruined wall, that is enough.
