URRRNN!!!
This is a 2x2 storage bin great for when you really want to slam things down onto your Gridfinity baseplates.
Thwomps can be stacked onto other Thwomps and can even wear other Gridfinity items like a hat.
Versions The basic Thwomp is a simple box. There is an optional insert for this version which makes storing longer items like pens/pencils/markers a bit easier.
There is additionally a Thwomp with a filleted edge similar to standard Gridfinity divider bins to help make it easier to retrieve items inside.
Print Settings I got the bets results on my setup using a .1 layer height with supports for Thwomp's face.
Disclaimer Thwomp's face extends beyond the normal demensions of a 2x2 Gridfinity item. As such, Thwomp will work best if its placed at the front of your baseplate. Not sure why you would want to risk Thwomp's anger by covering it up anyway.
