Classic "T" Puzzle

myminifactory

This is my entry for Make Anything's design challenge, so a like or share would be greatly appreciated. According to Wikipedia, the T puzzle consists of four polygonal shapes that can be combined to form a capital T. The base should remain blank until you've solved the puzzle, as it makes solving much easier. The base serves only to hold loose pieces and for decorative purposes; it is not a guide. The puzzle is moderately challenging and typically takes around 30 minutes to solve. If you succeed, try creating the other shapes shown in the second photo. As always, the solution will be withheld here (so you won't accidentally see it). Good luck!
