This meme has given me a lot of joy the last few days so I wanted to do my part to share it.

I reached out to the original modeler, tidiestflyer, on DeviantArt and he gave me permission to post the model here. Decided to go the extra mile and make it printable. Full cleaned up model is included, but won't print particularly well.

Pin/hole shape is from emmett, 75% scale. Four pins needed. The built in ones in the legs aren't great due to the print orientation, so I may try to fix them later.
Had some flipped normals issues, but I think they're all fixed. Mirroring the good version is possible in a few slicers if you run into this issue.
Full height is just shy of 100mm tall.

Printed at Fargo 3D Printing using Fire Engine Red and Snow White APLA from 3D-Fuel.

2018/01/19 update: Added different leg files. Pins shouldn't break, but may wiggle a bit. I added a few drops of super glue to stabilize them.
