You know, the ability to 3D print your own Glock is a really cool part of where weโre at with our technological capabilities. Finding quality parts is important, too, especially for the rails & locking blocks for 3D printed Glocks.
The rails and locking blocks are important because they ensure your gun functions as it should, preventing any malfunctions or injuries. They are also made out of metal rather than 3D printing filament, so you will need to get them from somewhere else.

To help you find the best rails and locking blocks for your 3D printed Glock project, Iโve broken down the offerings from four of my favorite companies to buy from. If you want the best, then make sure you keep reading along.
