    Installed on a modded CR-10, I had no trouble with the installation process and the quality is definitely outstanding.

    Another great Micro Swiss product

    Several years ago I purchased the Micro Swiss Direct Drive Extruder for my Ender 3 Pro for the POM wheels. It has worked flawlessly. I decided to make the move to linear rails. This product didn’t disappoint. Easy to install. The only improvement I would make is to make the trigger for the X limit switch adjustable. I had to redesign the X axis cover to allow the limit switch to be moved further to the left.


    Brilliant product, beautiful craftsmanship in the machining. Bolted straight onto my ender 3 whilst still using the stock hotend. Overall 10/10.

    Excellent Item

    This is a very good back plate for anyone wanting to upgrade their bed slinger printer to a linear rail system. Absolutely no complaints. Just make sure your carriage block is MGN12H, otherwise it won't be mountable.

    Made it fit

    I bought this for a Longer LK5 Pro that has been modified with linear rails and a top mounted spool holder. The extruder main frame had one extra hole drilled and tapped to mount the fan holder (one was already there) and two extra holes drilled and tappet to mount the fan cover. An aluminum bracket is being made to hold an end of filament micro switch to the top of the extruder frame. The extruder belt connection frame/ X-limit switch actuator fits well. I’ll forward photos when all the construction is done but so far this extruder is well made and a very close match to the improved Longer printer.
