Finding the correct springs, bolts, inserts and not 3D printable components are always trouble. I am trying to design almost all components 3D printable so as an update a good SPRING design attached.
You just need a glue and 3D printer!
Stamp is removable, you can print your own stamp.(Do not forget; stamp MUST TO BE MIRRORED)
Stamp surface 40x15mmx1mm Embosing h=2mm, w>0.4mm(0.8 and surface draft recomended)
You need to file the surface of the stamp in order to get finer printing.
Ink pad 41x23.5mm t=7mm(but you can adjust the tickness of pad). Made from vacuum cleaner motor filter.
Instructions: 1-Remove the supports and clean the rounded areas 2- Place the spring into the outer part and glue(super glue, hold the spring vertical and centered) 3-Place some glue on the spring(top flat surface) and compress iner part and wait. 4-Glue rotating part and stamp together.(Grind the surface of the stamp) 5-Insert the pad. 6-Compress the inner part and insert one pin to the hole and shift some and do same thing to the other hole. 7- Check if pad thickness is suitable or not. If not use thicker(or add layer). 8-Remove the rotating part and add ink. 9-Re-install the rotating part and start to use!
