Micro Swiss All Metal Hotend with Slotted Cooling Block for Wanhao i3 w/.4mm Nozzle

Took a while to dial this thing in. Still have some issues doing flexible filament but overall great end which is much more durable than the stock design. Not sure if I would buy this over as it limits my printers ability to print flex/TPU consistently but does allow me to print nylon and tougher materials with no worries

Best upgrade you can do for a wanhao i3/ monoprice maker select. Love it.

The Maker Select V2 was my first 3D Printer, and this hotend was one of my first upgrades for it. It has been running reliably for more than 2 years. Ive now got a small farm including 3x Maker Selects, Ender-3, CR-10, etc. and use the Micro Swiss all metal hotends on almost every single one of them (Creality machines use a different model). They are drop-in replacements, take about 10 minutes to install and work great.

Highly recomend this upgrade. I ordered it for my maker select v2 (wanhao i3 clone) and my prints look a lot smoother :)

made all my problems with printing PETG go away.

drop in fit for the maker Select 3d v2.

Upgraded to this set so I dont have to worry about PTFE liner decomposing. Install was a breeze but of course I broke one of the heating cartridge wires - my own fault, be careful when you do it. Print mostly PETG on Maker Select V2 with stock stepper and D4 drive gear, 0.25mm layers with 0.4mm nozzle at 60mm/sec head speed. Calibrated ESTEP at 3mm/sec which gives me a bit of a headroom for my head speed. It extrudes reliably, probably can push it even faster. Good experience so far.

Works great and my printing on my Wanhao Duplicator i3 v2.1 is super solid. You have to raise the hot end temp a big but its so smooth. Do take care to make sure the nozzle is up flush against the metal feed tube or you will get leaking inbetween that will cause clogs and envelope the entire unit.

Im only about 30 minutes into a print with this hotend, but so far it has solved all of my underextrusion issues.

I gave this item a 5 star for overall quality and for ease of installation and 3 stars for value for the money. I couldn’t get it to work right to save my life. I watched just about every YouTube video on how to install it and use it, etc. but personally have had no luck. I finally gave up and returned it for a refund. I was really hoping to get away from my hot end which uses the plastic tube as a heat break. Oh well, maybe you will have better luck with it than I did.
