Laser Grid – Modular Minimalist Pyramid – 3D Printable Vertical & Flat Connectable Support

Minimal modular laser grid – easy, fast and expandable

This minimalist modular grid is designed for quick 3D printing (flat or upright) and provides an affordable, lightweight and versatile support for laser cutting or engraving. The modular design allows you to connect all elements together, covering larger areas, replacing broken sections, or making custom setups.

Main features:

Two module types:

Flat/assembly: Print the modules (10cm or 20cm) flat on the bed, only 1mm thick, then snap them together and connect with printable pins (included) to create a grid as large as you need.

Vertical: Square modules (10x10cm or 20x20cm) printed upright and connectable via pins, screws or magnets. Ideal for maximum rigidity and fast setup.

Infinite connection:
All modules are designed to connect endlessly, whether same or mixed types, with printable pins, screws or magnets.

Super easy assembly:
No tools needed for flat modules/pins. Optionally add magnets or screws for extra hold on vertical modules.

Fits any workspace:
Build the grid to the size you need, add or remove modules quickly as needed.

Advantages over metal grids:

Cheaper

No laser reflections

Lightweight

Easily replaceable

Customizable

Printing tips:

For flat modules, use 0.2mm layer height or less for best fit.

Material: (White suggested) PLA or PETG.

Recommended infill: 20-30%.

Vertical version: can be printed without supports.

Included:

STL files for 10cm and 20cm modules (flat and vertical)

STL file for connecting pin

I added a 0.2 mm tolerance to the joints to ensure that the parts slide together easily without excessive friction, even accounting for typical 3D printing variations.

Tips:

You can add cylindrical magnets in the designed holes, or fix the grids with screws for extra stability.

Customize the grid length by adding as many modules as you need.

How to assemble the Modular Laser Grid

Print the modules (10cm or 20cm, flat or vertical version) as needed.

For the flat version:

Snap the modules together by fitting the notches.

Use the printable pins in the side holes to connect and lock the modules.

Optionally, insert cylindrical magnets or screws in the holes for more stability or easy removal.

For the vertical version:

Align the upright modules.

Connect them using pins, magnets, or screws as you prefer.

Arrange the grid to fit the size and shape of your workspace and workpiece.
You can connect modules in rows and columns to create a large, custom support surface.

Place the grid under your object for laser cutting or engraving.

Tip:
Modules can be removed, replaced, or extended at any time.
For extra stability, add magnets or screws in the provided holes.
