Want to have this awesome Branding Iron? Download the part and make your own tag. Please keep the following in mind; make the tag not larger then a square of 2 by 2 cm, centered from the middle of 3 bars. We recommend to extrude your tag 4 mm from the bars and any reinforcement you would like to add has an extrude of only 1 mm. Or the other way around, make sure your tag stuck out more than 3mm from the rest of the surface. Don't forget to mirror your image!
