Initially uploaded, the BOM list and installation video will be supplemented later

BMCU, indeed, I possess a ball bearing variant. However, its passive retraction mechanism consistently resulted in filament jamming, proving highly vexing. The alternative of electric retraction, necessitating additional circuitry, was consequently abandoned. Thus, I contemplated the elegance of a self-engineered solution. As June ushered in summer, a new design file was initiated. With the generous assistance of several esteemed individuals, I endeavored to construct a rudimentary prototype utilizing my nascent skills, which regrettably proved to be a discardable artifact. Subsequent reconstruction of the file, plagued by erroneous naming and assembly discrepancies, necessitated its re-abandonment. Rendered speechless by these setbacks, I sought further instruction from 'b', thereby finally attaining a successful resolution. This represents the fourth iteration, currently exhibiting no discernible anomalies, and is now released for preliminary evaluation
