Overview:

I wanted to replace old, poorly printed jumper wire holders with something that would work well with a tray I made from ½” birch plywood that is carved out in the middle for Clickfinity plates by NoWarranty (https://www.printables.com/model/452675-gridfinity-clickfinity-baseplate-no-magnets-univer). 

I found an adjustable gridfinity bin by gsgx and really liked it.  However, after printing it, I found the combs were difficult to insert, and I ended up breaking a number of the vertical pieces on the base.  I modified the design with the following modifications:

1. Modified the geometry of the combs to make the verticals a little beefier, added a slight gap for easier fitment, and extended the top parts of the comb to overlap and sit on adjacent verticals.  I haven’t had any break yet, and I have only been using PLA.
2. Created a version of the base with an insert for the verticals, so they can be printed in a stronger orientation (see build plate image).  This insert can then be glued onto the base using CA glue.
3. Created a 2x3 version for shorter wires.
4. Removed the magnet holes on the base as I do not use those.
5. Filled in the base slightly as there were small gaps between the grids.
6. Shortened the combs because I did not need that much height.

While splitting the model to test portions of the design, I realized the split version makes a good vertical storage option using double-sided adhesive (see pink version in image).  I glued in the comb with the tab at the top, so the upper section can rest on the adjacent vertical underneath to help support it.  I also added some CA glue to permanently install it and ensure it does not fall out.

Everything is compatible with Zach Freedman’s gridfinity platform: https://gridfinity.xyz/.

Printing:

Print in any filament you wish, but PETG works well if you have problems with PLA snapping.  No supports required if printed in the orientations shown.  However, if using the version with the insert, the insert should be printed with a raft.  I haven’t had great luck with just a brim.  The single piece version has been working great in PLA for me, so that is what I have been printing lately.
