Parametric Grid Generator

I wanted to learn more about openscad, so I started with this as one of my first projects…..Initially designed for an emersed aquarium plant project I'm working on, I decided to share my openscad code so folks can make any size/dimension of grid they need for whatever purpose they may need it for.

Parameters:

Pegs:

• Enable Pegs: Yes/No
• Peg Diameter
• Peg Height - How short or tall you want the support pegs to be (not related to grid height or line thickness)
• Support Peg Threshold Width - Adds side support pegs if width exceeds this width
• Support Peg Threshold Length - Adds middle support pegs if width exceeds this length

Dimensions:

• Grid Width
• Grid Length
• Grid Height - Height of grid lines
• Grid Spacing - Spacing between grid lines
• Line Thickness - How thick you want the actual grid lines

Some projects I'm using this solution for:

Plant risers (makerworld link TBD):

• The grids will allow the stem plants to sit in (but not completely submerged) the solution to grow roots and have something to attach to once the plants upright themselves.

Open Air Aquarium Lids (makerworld link TBD):

• Allows for open air to pass through to allow for gas exchange for growing floating plants (which don't do well in sealed glass/plastic lids due to the high humidity.

Aquarium bottom reinforcement (makerworld link TBD):

• When aqua scaping an aquarium sometimes adding “egg crate” grids are used to add more support for heavy rocks and other objects. I'm planning on printing some grids that are super thick and in TPU for a few upcoming aquarium projects where additional support is needed.

Aquatic plant/coral frag riser (makerworld link TBD):

Updates:

• December 5th, 2024 - V1.0.1 - Fixed issue where grid wasn't uniform when creating grids with odd sizes or grid densities. 
• December 2nd, 2024 - V1
  • Initial Release

Known bugs/issues:

• FIXED: Depending on the grid size you select some of the grid cutouts may not be uniform, that will be addressed in a later update.

Future plans (will be updated as more suggestions/ideas come to light):

• Add ability to select/change the shape of the grid beyond rectangles
• Add functionality for connectors to lock grids together
• Add “Snap-ins” to connect grids on top of one another
