Large Half-Size Thin Gridfinity Baseplates (K2 Plus 350x350mm)

Goal

This project aims to include every Gridfinity half-size baseplate (21 mm grid) that fits on a Creality K2 Plus build plate (350 mm x 350 mm). The largest half-size baseplate that fits is 16x16, which is 336 mm x 336 mm.

Baseplate type

These files use the thin baseplate style (5 mm tall), with no screw holes and no magnet holes.

File naming strategy

Each STL uses the pattern: baseplate_<X>x<Y>_half.stl

Where `<X>` and `<Y>` are the number of half-size grid units along the X and Y axes. All dimensions below are calculated as:

```

X_mm = X * 21

Y_mm = Y * 21

Original Gridfinity Size = (X/2) x (Y/2)

```

Size range

This file covers baseplates where X and Y are each between 1–16 half-size units, and at least one of X or Y is in 15–16 (smallest is 1x15 or 15x1, largest is 16x16).

If you need only sizes where both X and Y are 1–10 (up to 10x10), check the small range.

If you need sizes where X and Y are within 1–14 and at least one reaches 11–14 (up to 14x14), check the medium range.
