Welcome to the Open-Belt™! This buckle is designed to work specifically with heavy duty work belts and gun belts. The unique design of the buckle takes up minimum space to allow for placement of holsters and other equipment around the belt with minimal interference. The buckle permits the belt to lay flat, which reduces the bulk at the buckle found on most heavy duty belts. The belt was specifically design to work very stiff materials like reinforced leather or a coated webbing called Biothane. These thick materials do not bend well so frequently create a bulge at the belt. This buckle allows a thick belt to pass right through the belt with no need for a bend at all.
The buckle is designed to work with standard flathead 8/32 screws and 1/8" screw posts. Buckle designed for a material with belt width of 1.435 in.
The buckle was 3d printed for testing initially with good success. We did have an occasional breakage of a 3D printed version in use but most worked for weeks without issue before being replaced with a newer version of the buckle. 3D printing may work for you if your usage is light and you use a high fill (>85%) ABS print with an acetone vapor treatment after. Milled aluminum, Nylon, or Delrin is recommended for long term use.
The full belt is available for purchase at https://www.blackarchholsters.com/collections/accessories/products/belt and we will make parts available at openballistics.com shortly.
We typically print with the buckle on its left or right side for greatest strength. Currently using 2mm wall,top, bottom thickness with 85% infill with good success.
We have had good success with a cold acetone vapor bath of 1 hour, followed by 24 hour open-air drying.
