We were about to make a pork, but had no meat tenderizer (or tenderiser ?). Well, we had an Ikea Fixa hammer, so I made a meat tenderizer head accessory.

it's parametric (customisable / customizable), so you can use Customizer or edit .SCAD file to adjust:

• Hammer head length & diameter
• Material thickness
• Violence level (number & size of spikes)

Included .STL file is for those who have Ikea Fixa hammer (⌀ 26mm, ↨ 15mm) and don't want to mess with customizer.

Try not to use brim (use either raft or nothing). It's hard to remove the raft+supports and not to break item legs.

Ensure good layer adhesion and sturdy walls/infill so the part won't fracture on your food.

You should assure that the process is safe to your meat:

1. Use food-safe plastic like PLA. PLA is made of vegetable starch and it's food-safe unless it's dyed with a toxic paint. My PLA vendor assures my filament is biodegradable and food-safe.
2. Cover meat with a plastic bag while tenderizing (see the last photo)
3. Ensure good layer adhesion and sturdy structure so the part won't fracture and you have no plastic debris.

The good news are you don't have to worry about cleaning it — the part only weights a gram so it's easier to throw it away and re-print next time it's needed.
