M3 is the undisputed king of fasteners in the 3D printing and maker world! Whether you are modding your 3D printer, building a custom PC, mounting PCBs, or assembling robotics, you will constantly need M3 spacers.

Stop buying expensive assorted kits just to run out of the one specific size you need. Print exactly what you need, when you need it!

Key Features:

  • Perfect M3 Fit: Designed with an optimized internal diameter to smoothly fit standard M3 metric screws, bolts, and threaded inserts.

  • 17 Exact Heights (mm): 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 16, 18, 20, 25, 30, 35.

  • Wide Stable Base: The outer diameter is designed to provide a secure, flat footprint that distributes the load evenly without crushing what you are mounting.

  • Print on Demand: Takes only minutes to print a whole batch.

Printing Instructions:

  • Orientation: Print vertically (standing up).

  • Supports: NONE.
