AMS Lite Small-Spool Snap Retainer

A snap-on spool retainer for the Bambu Lab AMS Lite, designed to securely hold non-Bambu / small-diameter filament spools when the stock roller adapter is removed. The retainer snaps onto the AMS Lite shaft and provides a rigid stop flange that prevents narrow spools from sliding or falling off during retraction and spool changes. Designed for simple installation, no tools, and no interference with the filament path. Fit tuning:If the retainer feels loose or tight, adjust/modify the snap inner diameter by ±0.1 mm before reprinting. Shaft diameters may vary slightly between AMS Lite units.
