I like the metal upgrade, springs are great, and the twist nuts are cool but the extruder set was missing a bolt. I was able to reuse old bolts that I had, but be aware, you will be one short.

I had to use the old springs. The new ones are to long. I may need to trim to fit.

If you have purchased a 3-D printer and looking to do a quick and easy upgrade tomorrow not recommend anything better definitely makes 3-D printing much more enjoyable and having to constantly level the bed or having to deal with it not feeding properly no issues at all. Highly recommend.

Nice new part for my new printer.

The metal extruder is to replace the plastic one that the arm cracked. Warning the z will need to be adjusted as the springs are taller, making the bed higher. Failing to account for that the nozzle will drive into the bed and damage one or both. The bed remains level better after, but be aware to check first.

I would recommend! Just make sure to adjust the ESteps and z-axis sensor after for best performance. (Very important steps)

installed the extruder upgrade and halfway through the first print the screw that hold the bearing came loose . the aluminum was poorly machined and the screw came out with the threads .... basically its useless .... seller wont respond to inquirey .

So nice To replace original plastic one with a beautiful metal one, same goes for the bed leveling wheels.

The aluminum parts are well made and the upgraded bed leveling wheels are great! I used a little dot of Elmers glue between the bottom of the screw heads and the metal bed plate to keep them from spinning. It didnt stick to the metal super well, but it made enough friction to keep the screws steady.

This is a good deal if thats all you are after. After making my purchase I found better deals that included Capricorn tubing, spare nozzles, spare bowden couplers and clips and all sorts of stuff for just a dollar or two more.
