Gridfinity Holders for Cleco Fasteners (Vase Mode)

The idea for these started out after I printed a different Gridfinity cleco holder yesterday, that's available here on Printables.  I thought it was a great model, and well designed, but I also identified several changes I would like to make, so I planned on designing my own version whenever I got around to it.  As coincidence would have it, at the same time (on another printer) I was printing a case tray for cartridge reloading, that was designed for printing in vase mode.  Which gave me the idea to try to design a cleco holder for Gridfinity that can be printed in vase mode.

Major props to @brass_ring who has published so many awesome reloading trays, cartridge boxes, etc.  Having never designed anything specifically for vase mode, I studied the model of his tray I had just printed, to learn what needed to be done.

I ended up creating two different models.  The first one uses two grid squares, and has provision for magnets, because it is self-evident that Gridfinity should always be designed to accept magnets.  Which should be sized for a press-fit.  Like my other Gridfinity models, it uses 6x3 magnets.  The good news is it packs 18 clecos into 2 squares.  The downside, and it's a big one, is that because of the way Gridfinity bases work, the vase mode can't start until you get above where it bridges between the two squares.  Meaning that the total number of bottom layers used must equal 5.8mm, which is 20 bottom layers at a 0.3mm layer height.  Ugh.  This is time consuming and wasteful of filament (because it all has to be solid infill), but as long as your slicer setup is correct, it prints fine and I think I like it better than the second model.  Because magnets.

For the second model, I cut it down to a single grid square and eliminated the magnets.  This allows a more reasonable number of bottom layers; I would suggest a number equal to 1.20mm, i.e. 4 bottom layers at 0.3mm layer height.  Two of these print in less total time, and use less material than one of the 2 square units.

I would recommend printing either model using at least a 0.6mm nozzle at 0.3mm layer height.  Set your extrusion width to no more than 1.20mm. When I tried slicing at 1.30mm extrusion width, Prusaslicer threw an error that went away at 1.20mm.  If you print the 2 square model with magnets, be sure to use bottom layers totaling 5.8mm.

I printed both of the models shown using Overture matte red PLA on a Bear upgraded Mk3S+ and a 0.6mm nozzle, 0.3mm layer height.

In case anyone wondered, the model on the left in the third picture is the other user's cleco holder that I printed originally.  This photo is posted for comparison purposes, mainly because it shows the height differences between it and both of mine.  If you are keeping these in a drawer that is height limited, the single square model will give you the best vertical clearance.
