Good upgrades for 3-D printers.

I bought a printer that was not a Creality brand and have had nothing but headache after headache with it. Ive been slowly swapping out parts on it with the Creality brand parts and each time there is a leap in performance. What was a clicking extruder gear and a bed that required leveling ever print are gone. Theres just something of a better quality with these parts. Only recommend Creality.

The springs were the wrong size.

Awesome addition. I bought mostly for the tighter springs, but when i went to replace the extruder covers i noticed that the plastic pieces i was replacing were cracked and about to break! highly recommend these parts. note: you will have to move your Z-stop up a bit due to the change in springs and wheels.

a must purchase upgrade. Takes away some problems and hassles. Makes level the bed easier and not having to level the bed before each print.

The springs are amazing, add in BL or CR touch and youll almost never have to level your bed again. The extruder upgrade is needed no matter what. The oem plastic WILL break.

The springs alone increase the quality of life with your printer. I rarely have to keep leveling the bed (even with a BLTouch). Having an all metal extruder is also a must have.

Springs are too short for the bed. The gear for the extruder motor on the Ender 3 can’t be removed. Save your money for a CR or BL touch and just buy the all metal extruder parts.

I have 4 printers. 2 with a similar red kit and this kit which is the silver ones. The metal extruders seem to be the same or same quality on each however this kit has better springs for the bed. These springs are a little beefier and seem to hold the build plate level a little better. Less micro adjusting needed. I would recommend to get some Capricorn tubing with this kit as well and you should be set

I wish I could review the entire kit but the only usable item for me are the red tensioning wheels. Wheels: great Springs for wheels: way too long to be useful anywhere. Extruder: worthless. I’ve had to use stock screws, specialty parts and it still won’t feed filament. Update May 11: despite best efforts, none of the parts were usable for my printer. The wheels would cause the bed to raise over longer prints, failing multiple larger pieces, extruder assembly never did function properly. I’m keeping them as spares just in case a third machine will work better, but as of right now, not the parts for me.
