Convolute/Parallel Kraft Paper Tube Roller with Adjustable Guides

This is a simple, easy-to-use, easy-to-print convolute or parallel tube roller for 1.5" inner diameter kraft paper tubes.  The roller has separate, adjustable guides that make wrapping the paper around the form much easier as well as a small slit to insert the kraft paper into if you need some help getting started.

Key Features

• 1.5-inch inner diameter design for creating 1.75" kraft paper tubes
• Interior geometry / inner perimeters added for strength
• Removable paper guides with groove showing correct thickness
• Slit-and-flap mechanism for easy tube formation
• Versatile use with kraft paper and adhesives like wheat paste or Titebond 3 wood glue

Printing Instructions

Print one roller and two guides, no supports needed.

You should use a wide brim on the roller - I use 10mm. 

Usage Guide

Insert a small (1/8" - ¼") flap of paper into the slit on the form.  Slide on both paper guides, flush with the top and bottom of the paper in the slit.  Put a small piece of painters' tape or something on the guides to keep them in place.  Rotate the form so the paper is being rolled on from below, and the top is rotating away from you.  Make one and a quarter wraps before applying adhesive in a thin layer on the top surface of the kraft paper.  Keep tension on the paper so the tube rolls tightly.  Once the tube reaches the thickness indicated by the groove on the paper guide, slide the tube off with a twisting motion (cut the extra paper if there is any). 

Tube stuck on form?  You applied glue too close to the start.  You need at least 1 ¼ wraps of kraft on the form before brushing any adhesive onto the paper.  Let the tube dry completely (1 - 2 days, depending on conditions), then smack it lightly-ish on a counter or something to break the adhesive so the tube can slide off.
