Great little hammer for knocking prints off the bed, or for "persuading" some into a tight spot without mashing it up.
There are two sizes of hammer, the handle for the small and large hammers are almost identical and probably interchangeable.
Including a Bambu build plate version with presets.
I'd recommend printing the head in TPU at 100% infill and the handle in ABS. Makes for a super sturdy hammer. Credit to Walter for creating the original model: https://www.thingiverse.com/walter
