It costs a fraction of commercially available scrub brushes. In less developed regions cleaning tools such as a scrub brush are indispensable. This brush is also customizable allowing any size brush to be made easily for any application. It is printed using a bridging technique.<ref>Spyder Byte – Bridging Techniques, SPYDER3D (Dec16, 2014) Available: https://www.spyder3dworld.com/spyder-byte-bridging-techniques/</ref> This project was inspired by other fully 3d printable bristle designs<ref>Nail Brush - Fully 3D printed! , Turbo_SunShine (Jan 14, 2019) Available: https://www.thingiverse.com/thing:3355727</ref><ref>Bouldering Brush v2, Turbo_SunShine (Feb 7, 2019) Available: https://www.thingiverse.com/thing:3410740</ref><ref>Room Broom - Spyder3D World, 3DKreashunz(July 7, 2018) Available:https://www.spyder3dworld.com/item/room-broom/</ref><ref>Dust Brush & Pan (Fully 3D Printable), Superbeasti (Oct 1, 2019) Available: https://www.thingiverse.com/thing:3890384</ref><ref>Bridging: 3D Printed Paint Brushes - Spyder3D World, 3DKreashunz (July 7,2018) Available: https://www.spyder3dworld.com/item/3d-printed-paint-brushes/</ref><ref>Master Jedi YodaHawk - Spyder3D World, 3DKreashunz (July 7,2018) Available: https://www.spyder3dworld.com/item/master-jedi-yodahawk/</ref> .
