I’m printing multiples of a panel-like model which are set on edge.
The models tend to wiggle under the hot end near the top.
Is there any way for me to join these multiples along an edge with a removable support-like connector, to make my multiple panels stable like a block?
I could paint supports under the honeycomb apex, but joining these along the flanges at the edge would be a nice solid clean break point. Simply drawing vertical support enforcers results in supports nearly as vertical as the prints themselves… a proper support would come in closer to a 15d angle to add some stability in the weak dimension.

Go back to your 3D software.
Clone the model as a part.
Build small supports that are 0.2 to 0.6 mm square and have a 0.3 to 0.4 mm gap between them and the models.
Export
Print.
That tiny gap is enough for the printer to drop a tiny bit of filament and create a very week “Bridge” between the models. When you go break the models apart, you are left with a tiny dimple to clean up.
Or you could use PVA supports and just drop the model in the water afterwards. Kind of fun watching the supports dissolve.
There’s no built-in Studio feature for horizontal supports/joins like that. Someone requested similar feature over at GitHub recently. You can paint support points on vertical surfaces, but yea that results in some long supports, as you found, and the slicer has no concept of “sharing” support bases between objects either.
I think in this case you may be best off adding the break-away connectors manually to your model. Ah, yes, something like Remote already suggested.

Also, slow the print’s Y-Axis travel way down. avoid “jerking”…
hhmm I can’t remember if that’s a thing or not. I’ll have to go back and read the controls again.
Scratch that, y-axis only is not a thing. you’ll have to slow the whole thing down. Maybe turn your models so they are directly facing the y-axis of travel.
I was printing a bunch of mounting channels for LED strip lighting awhile back and had this exact issue - they have exceptionally small footprints but are quite tall.
To solve this, I arranged them (in CAD) to sit corner to corner to form a circle, when sliced the parts still get wall loops that are independent of one another, but when printed the proximity results in “almost” adhesion and a much more stable overall print.
I’ve also designed thin “helper” shapes in some cases to provide support when needed. Picture of that shown here:

It’s a model on Makerworld, so I guess that means export as STL, arrange the group with support in freecad and re-import, but I believe the stl conversion loses resolution, no?
You can clone individual parts in Bambu Studio and reposition and rotate them without having to export. You can also create primitive shapes to act as extra support structures.
STL to FreeCAD come out as mesh’s and FreeCAD does mesh’s as well as butter does siting on blacktop on a Phoenix summer day. So if this isn’t your personal model, keeping it to Bambu Slicer is probably the best you can hope for. Rotate the part to run parallel to the y-axis, build a little shrine around your printer, light some candles, and as you start the print, pray non stop until the print is done. or follow the advice CarbonForge is sharing.
