Spiro Card - Dụng Cụ Vẽ Spirograph Mini

This is a bank card sized spirograph with snap in gearwheels. The model measures 85.6 mm x 54mm x 2mm. Thin enough to fit in a wallet! 

Prints well in PETG or PLA with the standard 0.4mm nozzle at 0.12mm layer height. 

Should be printed using 100% infill for strength and stability when drawing.  

Print two in different colours to add some contrast. Makes a great gift!
