It doesnt matter the size its how you use it...
Hammers that is. I used a rusty old nail hammer for installing magnets so I decided to upgrade to a 3 dollar hammer from Harbor Freight. Honestly it's perfectly sized for anything that I do with 3d printing. And after a caffine induced passionate design session in Onshape at 1:35 in the morning I produced this monstrosity.
Notes: the additional hole on the top is for a 6x2 mm magnet to hold the hammer in
Here's the link to the hammer on Harbor Freight in cause you need to order it online. It's fun to have around the house too https://www.harborfreight.com/8-oz-stubby-ball-pein-hammer-95930.html
