this bracket holds the feet, lines them up, to allow applying glue, slide the base of penguin forward, and glue the feet to the penguin. NOTE, you need to cut off (possibly) the back corners of this guide, they might catch the feet slightly.
but this makes it much easier to apply super glue (gel might work better) to the feet, once they are lined up,then line up the penguin tail, and slide forward, and the feet easily get glued to the base.
I imported the base into tinkercad, cut a couple holes in it, sliced the top off, and made a shell box from the original base. This was a quick project, not one of my cleaner ones, but it actually works ! (was easier to slice the body in tinkercad than in fusion 360)
if anybody wants to modify it, feel free to improve it !
The author remixed this model.
not a remix, but a new part to use,for gluing the penguin feet
