This a holder for a dimmable LED light. You see it on my Original Prusa i3 MK2 in the photos. I have two versions for download, one for a 30mm cooling fan (for MK2) and another with the parts for a 40mm fan (for MK2.5 and MK3).
It swivels to aim the light where you want it. The Floating LED Light has two hinges for adjusting the position of the LED. These hinges allow you to aim the light and swing it in or out.
You simply touch the back of the LED to adjust from off to super-bright. You can even do this while the print is running!
More info and videos on my web site at Maximpulse.com.
Easy to install. Remove two screws from the fan and replace them with new screws 7mm longer. Super easy to install. The included clips hold the USB cable to the existing wrapped power cable.
All the parts are here to print out and make your own.
I also have sets of parts for sale on my Etsy store
You can either order
- the complete set of printed parts, USB cable, clips, LED, screws & nuts and zip-tie (17 pieces) or
- just the LED, screws & nuts and zip-tie (8 pieces). You print the plastic parts and supply your own USB cable.
Or you print your own parts and then go to eBay and search on "dimmable LED touch USB" and order the hardware from China. Shipping is around 3 to 6 weeks from China.
I have printed the Floating LED Light in PLA, but pretty much any kind of filament would probably work.
I just uploaded some new files.
One is called "holder for 40x40 fan MK3" and it lifts the LED .12" higher. This for the MK3. The collection of all the parts in the file "floating_LED_all_parts_MK2_30x30_fan.stl" contains this new part.
The other is called "holder for board with more vents" and it has a couple extra vent slots as suggested by a user.
I've been printing these in PLA. ABS should work, too.
I print these at .3 mm layers, but obviously smaller layers would work, too.
Drill out the holes, if necessary
Sometimes the holes for the 3mm screws come out a bit squashed.
That is remedied by drilling out a 3mm or 1/8" hole.
Or a little filing with a small round file does the trick, too.
The screws required are two 3mm x 25mm, two 3mm x 30mm and two 3mm nuts.
I purposefully made the recesses for the nuts a tight fit. The nuts will snap in, but they may require a tap to seat them.
I have how-to videos on my website at Maximpulse.com
You might want to watch them for assembly instructions and to see how to snake the USB cable.

How this improvement came about
I love my Prusa i3 MK2 printer. It has made wonderful things possible for me.
But there is always a shadow under the extruder which means it's hard to see what's printing.
So I came up with an LED light that floats along with the extruder, illuminating the area under the nozzle.
These improvements were a bit tricky as Josef Prusa didn't leave much room to fit anything additional on his marvelous printer.
