This 3D printed mallet shows the strength of 3D printing. By printing at 25% infill with PLA-PHA, it’s possible to print a mallet capable of driving tent stakes, nails and assembling shelves!
I designed this in AutoCAD 2014 (Which is now Fusion 360) and this printed at 0.4 mm layer thickness. While you can see every line, that also means you have a textured grip for the mallet.
For weight I used a stack of fender washers. I used these instead of BB’s in case the print failed their would be less mess.
I printed this back in 2017, and have used the mallets for various fairs to drive tent stakes, assemble PVC shelves, and other task where you need to wack something. I printed a 2d mallet in Nylon as well!
