These stabilizers will fix the loose rods in the Z-Axis of the Monoprice Select Mini 3D Printer. This is part of an ongoing project to upgrade the Mini on a budget!
Print these brackets with the flat side down, then install them on your rods under the factory brackets. Make sure the raised grips for the rods are facing towards the underside of the brackets (away from the printer sheet metal).
For detailed instructions, follow along as we tweak and mod our Monoprice Select Mini 3D Printer with cheap upgrades to make it into a precision 3D Printing Instrument, on our Hack-a-Day Project page here: https://hackaday.io/project/14823-maximum-3d-printer-bang-for-the-buck
Print these nice and slow, to get them as accurate as possible. This will guarantee they fit properly and last forever.
