Openprinter allows easy cartridge refilling to reduce costs and limit waste, giving users control over ink consumption.
It offers independent use of black and color cartridges, eliminating frustrating blockages like 'Cannot print in black because the yellow is empty'.
Users can print in rich black or vibrant colors with single cartridges, or use both, and choose between standard sheets or versatile paper rolls for banners, strips, and customized formats.
The author has created an extensive instructional guide for designing and sewing fabric sphere panels, primarily for juggling beanbags but adaptable for footbags and other cloth balls.
The guide spans over 750 pages, divided into separate PDF documents for each panel structure, with a root document providing an index and supplementary chapters.
It caters to both beginners with ready-to-print patterns in six sizes and scaling instructions, and technically-inclined readers with mathematical formulas and design theories.
