I made two versions of the handle, one for vertical printing and one for horizontal printing. Use the one that suits you better. For horizontal printing, you need to print two pieces and glue them together. For vertical printing, add a few millimeters of border and support.

Everything is printed easily without the use of glue, and all parts are reliable and have been tested in home use. It will take a short amount of time to adjust the parts.

Supports must be included under the roller itself.
