Spool Roller - fully adjustable and collapsible

I wanted to create a spool cradle/roller for a dry box I am making. I had a couple of odd sized spools, so I figured that I'd create something that would work with every spool size that I may ever encounter, except those larger than 1kg.A brief internet search revealed that the largest commonly available spool diameter seems to be 210mm, and the smallest 160mm. Widths vary between 80mm and 50mm, but this is less of an issue.This roller will adjust between 210mm-160mm in 5 increments. This should be sufficient to allow any spool falling between those two diameters (and possibly spools that are slightly larger or smaller) to be used. Simply find the setting which seats the spool securely whilst keeping the bottom of the spool off of the ground.The roller also collapses when not needed, and no glues or fasteners are required.Print the following files in the material of your choice (I used PLA at 0.20mm layer height)1 * Cradle - right side1 * Cradle - left side2 * Sliding support3 * Cross
