This is a remix of TheHiveMind's scuttle crab model. From what I understand there used to be an exploit in the League of Legends client that let you rip models from the game. This happens to be one of those models. I printed just the unedited model 3 times with various settings and it really struggled with a lot of parts. In this edit, I've re-meshed the original STL, added a hole for a stand, and quickly designed a stand.
I haven't printed it yet only because my printer is busy printing an enclosure for my Raspberry Pi 3 B+. I am planning on printing it tomorrow (9/15/2019) at 250% scale with an estimated time of about 16hrs.
To actually print this model you're going to need to cant the whole crab forwards about 30degrees and use supports on any overhang above 25degrees.
Remove the support really carefully with flush cutters like the ones that come with the Ender 3 and a pair of needle nose pliers to remove any loose pieces of support.
My sister is going to paint the finished product after I sand it and prime it for her. I'll update this with the final product.
