Why do you want this upgrade?
Upgrade your heated bed to heat quicker* (if you have a stock external MOSFET or none at all) with our high amp MOSFET board. You can use this with heated beds or hotends (if you are wanting maximum protection). The main reason to use an external MOSFET like this one is to remove the high amp load from your bed off of the control board and put it onto this MOSFET module. Compatible with PID regulation (used in our firmware). Works with any printer that runs on 12-24V on the board and heated bed. Also works with ESP, Arduino, and Raspberry Pi boards.
Technical Information
Rated up to 30A @ 3V-24V DC with fan cooling. 20A max load with no fan. Large Screw Terminals for easy wire connection and works great with crimp ferrules. Includes 12″ Control Wire – Connection from MOSFET to Printer Board
NOTE: Before installing the MOSFET make sure the heatsink is firmly adhered to the PCB. They can sometimes get knocked off during shipping. Just press on the heatsink and it will bond to the PCB.
*Quicker heat-up times are based on testing in-house and customer feedback when using basic control boards or stock external MOSFETs. Not all printers will see quicker heat-up times. Other factors such as using PID or Bang-Bang regulation will also affect heating times on stock and our MOSFETs.
Installation, Wiring Diagram, & STLs for Mounting
STL files to mount to your printer (Universal and Creality Specific options are available) are included with purchase. All mounts use M3 screws to attach the MOSFET to the part (screws not included).
Part Fitment/Installation
This is a universal 3D printer part. That means it will work on almost any 3D printer (check your printer voltage and part voltage) with the correct mount for your specific machine. Thingiverse is a wonderful place to locate mounts and we also have printed parts in our shop for some universal parts.
It is up to you to determine and select a mount for your specific printer model (or design one) to install this part on your machine and wire it up to your machine (if applicable). You are welcome to Contact Us for recommendations for your particular printer model for mounting options that are available online if searching yourself does not yield any results.

Great little mosfet. The heat sink had fallen off in shipping but luckily I had some thermal glue so no biggie.

Hi there Jesse. We had this happen one time when we were using a mosfet in a build. All you need to do is just press it on to the PCB firmly and it’ll stick. We suspect the manufacturer wasn’t pressing hard enough on some of them.

I installed one of these on an Ender 6 and used one of the mounts they have linked on the install page for the product. It fit perfectly on one of the 2040 extrusions in the bottom of the printer. The bottom cover goes on still without any interference.

I’ve installed two of these. One on an Ender 3v2 and one on an Ender S1. A little tricky to find a place to mount, but work really well. They both heat up faster and seem to stay a lot more consistent at the temp set. I will be installing one on every printer I buy.
On Ender 3v2 I found a mount on Thingiverse and mounted to the underside of the 4040 extrusion. I had already installed raised feet on it to try to improve airflow. On the Ender 3S1 I used the TH3D mount and used a spot next to the mainboard. There was a spot with a raised area that I could use a couple of zip ties to mount it.

I’d like to definitely recommend these FETs for any printer no matter what bed size you have. Honestly for a piece of mind anyone should get these.
But also be prepared to extend your power wires a bit. I had some spare high quality RC hobby DC power cables laying around and some screw connectors and ferrule for each end. Make sure your crimps are nice and strong before you connect anything and I used a bit of heat shrink on each end to tidy things up. Make sure to get higher quality DC power cables from a RC hobby store, I don’t trust the cheap stuff, I did some measuring and found that the cheap knock offs don’t have copper like they used too. I bought two of these, one for my Ender5Pro and my Ender3Pro.
I would also use a bit of thermal paste between the heat sink and FET, I used some artic silver. I ran my bed at about 85C for about a few hours and noted that the heat sink temp on the FET would get to about 40C, no where near hot enough to cause issues, which is great and plenty of room for expansion for higher heating elements. I ran a PID on the bed and some of my values changed but not by much, though I’m using Klipper firmware as this is the best 😉
Overall, great little upgrade.

Had no trouble installing this device. It is well made and I feel much safer having this on. My bed wires used to get a little warm and now they don’t. I don’t understand why, because the bed heats up faster. But I am not going to question it. The Creality Mosfet had some dark, appearing to be burned or stressed out marks and it did not smell all that good. Perhaps I had a bad one because my printer is only 2 months old. No more worries now

Excellent product that is made well and provides extra peace of mind. Installed on a Maker Select V2, and is much recommended. Install guide is simple to follow and wiring is easy. 10 minute install.

Easy installation but haven’t noticed any material change in the bed heat-up speed on my Ender 5 with EZABL. Manages rock solid temps and will go higher than stock.

This upgrade makes a marked difference in the performance of your CR-10 heat bed and for a small investment. Highly recommend for anyone with a CR-10 printer.

replaced stock mosfet on heatbed with this one, bed heats up quicker then the old stock one on my Cr-10
Byron –
Easy install on a Ender-3. I replaced all stock wires and xt60 connectors with beefier higher quality parts. Noted a huge difference in warmup time.
Tried printing ABS with the stock mosfets and layer separation was a huge problem, as I could only eek 90c on the bed temperature. Now it cranks to 120c no problem, fast and stable and ABS prints are much improved.

Works great so far, not too hard to install. Bed heats up faster on my CR10. I’m thinking of buying a second for the hotend.
