Gridfinity Template - Barcode Labs Mod

This is a modified version of Zach Freedman's Gridfinity template. A full rebuild was performed from scratch, following the standards documentation. The sizing of this version is not 100% identical to the original template, but all the parts should be compatible.

This is a work in progress, there may be issues that have been overlooked in this document. Use at your own risk.

If you notice any errors or come up with any other ways to simplify, please let me know.

The Template Files

Fixing parametric feature

The original template utilized patterned bodies to create the Gridfinity container. This approach is problematic in Fusion 360, because the patterning feature does not automatically combine bodies. Oftentimes, an additional step is needed to combine additional bodies into the primary component.

To fix this issue, a different approach needs to be taken. Instead of patterning bodies, timeline features should be patterned instead. This will allow for a single parametric body to be outputted after adjustments with no additional need to combine.

Standardizing unit height

In the original parametric file, one unit produces a box roughly 25 mm tall. Following the standards documentation though, a one unit box should be roughly 18 mm tall.

A standard base should equal 7 mm without the stacking feature added. Each additional unit should add 7 mm. If the item is capped with a stackable lid, that height is appended after the fact.

Simplifying the CAD file

Having the luxury to work from existing standards allows for a cleaner CAD file. I was able to devote time to keeping the file as simple as possible. The added simplicity should make it easier for most users to understand how the file is put together and how to mod it. All sketches were label. The parameters were kept to a minimum since.

Bridged magnet holes

The original holes for magnets are simple extruded cylinders. When the slicer does its job on these holes, it doesn't support them very well. This issue can lead to sagging and drooping print lines that need to be cleaned up after the fact.

This one is an easy fix. By adding one additional extrude step equal to the standard layer height (0.2 mm and) the slicer will now run straight lines across the cylindrical opening prior to adding additional infill. This will allow for support less prints that are cleaner.

Hexagon press in magnet holes

Hexagonal press fit magnet holes are easier to install magnets, have a looser standards for what will and won't fit, and also retain better than their circular counterparts.
