A simple design that replicates a standard folding magnifier, often called a linen tester.

This is in four parts that easily fit together to form a folding device held together with four M3 30mm hex head screws.

• Required: 
• Four M3 30mm screws.
• A magnifying lens of 60mm diameter commonly found on sites such as eBay for a few pounds. 

No support required. I used an infill of 12% and two outlines on all suffuraces.

Wil take a few hours to print.
