Introduction

One thing the Prusa Enclosure lacks is illumination. This is quite if you use something like a Beagle Camera as it will not see that well in darkness. Because of this, I wanted to mount some LED strips in the enclosure.

I have made some bad experiences with the adhesive on these strips, so I decided to not go the sticky way. Instead I designed a holder for the strip, and as I didn't want to screw around with the enclosure (pun bad, but intended) I added some magnets.

Finally, I didn't want to fiddle around with an additional PSU, so everything should be connected to the PSU of my Mk4.

What You Need

If you want to recreate my astonishment at the pretty light, you'll need to print the following:

• One each of “end part A” and “end part B” per light bar
• As many pieces of “middle part” as you need for your application

The end parts are 100mm each, the middle part is 200mm. Just print enough of the middle parts for whatever you want to do.

In addition, you'll need the following extra components:

• Enough LED strip that is 8mm wide (24V if you want to use the Prusa PSU)
• 1x magnet (10x4x2mm) per end part
• 2x magnet (10x4x2mm) per middle part
• Some kind of 2 phase wire for wiring the strips up
• 2 M4 cable shoes for connecting everything to the Prusa PSU
• Soldering iron, solder, flux for, well, soldering

So, if you want to copy exactly what I did, this is your print/shop list:

• 2x End part A
• 2x End part B
• 2x Middle part
• 8 magnets
• ca. 120cm of cable
• the cable shoes

Assembly

I recommend you start with removing the supports from the holes into which the magnets go. Check if your magnets sit really well in the holes - if they don't, add a drop of superglue.

Next you assemble your light strip holders. I guess it's hard to mess that up given the shapes involved.

Now the strips need to go into the holders. You can try to push them through, but I think that is a really bad idea. It's better to lay the holder on the table in front of you, than lay the strip on the holder. Slide one side of your strip into the notch in the holder and then press the other side of the strip in with your fingernail. The entire process took me less than a minute for two holders. Oh, and don't even bother to remove the foil from the adhesive - it's not required to do so, the strips will stay in place without any of that glue. :)

Nothing much to say about the soldering, just look at the picture I made of the result and everything should be rather obvious.

If you want to power this from the Prusa PSU, attach the cable shoes to the end of the power cable. Remove the PSU cover which is held by two allen screws. Loosen the first and the third terminal connector screw, slip your cable shoe in, tighten the terminals and re-attach the PSU cover.

A Shameless Reference to Another Model of Mine

You probably want to route the cables inside the enclosure and you might already have searched for some zip ties. I personally don't recomment that as it kind of defeats the mobility of the magnetic solution. Better print some of my magnetic cable clips that I designed specially for this very purpose: https://www.printables.com/model/619484-magnetic-cable-clip

Please Publish Your Make Here

This model may be trivial for the pro printers out there, but for me who has started 3D modelling and printing just two weeks ago, this is really cool. I would be terribly sad if this model got no likes or makes - so if you like it even a little bit, like it and publish a make. I would very much appreciate it!
