The file 'Kotobukiya Variable Frame System Action Base Adapter 3D Printer Model' is (stl) file type, size is 5.8KB.
I Had a Kotobukiya stand long ago and it destroyed itself so I don't intend on getting any more stands from them. Bandai on the other hand has many many stand options. I made this with an action base 4 in mind but it should work with an action base 1 with no problem.
NOTE
You can see in picture 2 if you use a clear base without rescaling the model a little it will cause the stand to develop some fractures. It's not broken or loose, but It is worth mentioning
