This belt buckle is designed for making a belt out of synthetic belt straps.

Many straps sold on Amazon are 30mm wide. They usually come in two thicknesses: 1.2mm and 2.0mm. Personally, I prefer the 2.0mm variant for my belts, as the thinner 1.2mm fabric tends to develop wrinkles over time. Here are links to the specific materials I designed this buckle for, but you will find many similar products in other colors on Amazon too:

• Black 1.2mm strap sold in 3 metre rolls: https://www.amazon.de/gp/product/B00KKU6L7Q/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=bergland-21&linkId=de9a478b5e7fc331d324c0922e72c46b
• Black 2.0mm strap sold in 10 metre rolls: https://www.amazon.de/gp/product/B00KKU6L7Q/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=bergland-21&linkId=de9a478b5e7fc331d324c0922e72c46b

A belt usually is 90-110cm long, depending on your size.

I've put up a video on YouTube which explains how to assemble the belt!rnrnhttps://youtu.be/WFBYDQT83NA

Remove the supports (the thin vertical bars) from the two holes on the sides of the buckle.rnrnPut a drop of glue into the holes in the latch. Insert the latch into the buckle, then push in the two pegs from each side. To prevent any excess glue from jamming the latch, rotate it a couple of times while the glue dries. As the pegs are a tight fit, it helps to carefully push them in with a vise (such as this one: https://www.amazon.de/gp/product/B002LIOTX8/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=bergland-21&linkId=44dfab3878e9ec99b7dd8080b1243ead&language=de_DE)rnrnCut off a 1m long piece of fabric stock and apply glue to a 1cm wide strip at one end. Fold the strip around the crossbar to form a closed loop. Use a clamp to hold the fabric in place while the glue dries.rnrnApply a drop of glue to the recess in the buckle on each side. Insert the crossbar with the attached straps into the recess in the buckle (the ends of the crossbar should face upwards). Leave everything to dry.rnrnGrab the other end of the belt fabric with pliers and briefly melt the cut with a heat gun to prevent the fabric from fraying.
