Drop-in stem for MMU Grumpy Pumpkin

I recently printed the Re-Mix of MMU Grumpy Pumpkin by Cube_3D but only realised 10 hours into the print that the stem was meant to be printed in-place.

This is a modified version of the stem file that can be printed separately and slotted in. However, you will need to scale this in your slicer to match the size of your print so make sure you measure it up first.
