Printed on bias for strength.

Pins buildup from a solid “H” base that should require no support or brim.

Solid full gusset provides rigidity, back stop for shelf holds pin in place.

Size is 0.25" or 6.35mm, but can be easily resized.

For example, to produce 5mm pins, resize the print uniformly by 79%

Recommend printing one to check size, scale the print as necessary, then clone as many copies as needed.

Designed to print easily without support, though glue stick may be necessary depending on fiber material used.
