Style A = Has mounting holes for screw-mounting

Style B = No Holes for mounting with double-stick tape

Uses 15mm (0.6") glass marbles that need to be inserted before the print finishes, ideally right as the opening is just beginning to narrow.

Bed Size 200x200 can print up to 250mm size

Bed Size 300x300 can print up to 400mm size

Bed Size 400x400 can print all sizes

Depending on the size you're printing and the size of your print-bed, you MAY need to print at an angle.

While it's theoretically possible to use 3d printed 15mm “marbles”, I wouldn't recommend it for a few reasons.  One big reason is improved smoothness.  The MAIN reason is they have the ideal weight to pinch the paper.  Ball Bearings may be smooth, but their weight can sometimes be an issue.  Printed “marbles” tend to be rough and might not have enough weight to hold the paper.  If you try an alternative to marbles, let me know how it works.
