Heavy-Duty M5 Hardware Set: 4 Bolt Variations & 3 Matching Nut Styles

This set features four bolt variations—two at 16 mm and two at 21 mm—all with a 5 mm diameter, accompanied by three matching nut styles. Designed for efficiency, the entire 7-piece set prints in approximately 21 minutes, without the need for supports.

I have extensively tested these, in various PLA blends across multiple applications, with great success. For projects requiring extra durability, I recommend printing in PETG, and/or with increased wall counts or higher infill percentages.

I hope these prove useful for your next project!
