+**BOM:**

 - Some cables
-- A soldering iron
+- A soldering iron and some solder
 - JST-XH Crimps
+Notes about the WS2812: 30 leds per meter fits, but you will only have a led in every second diffuser. 60leds per meter is the perfect fit.
 
 
-Print guide:
+**Print guide:**
 
-Print 9 normal and 9 mirrored.
-I mixed 16 and 17mm because the spacing on these are not exactly what you'd call accurate.
+Print 9 left and 9 right.
 
 
-Preparation:
+**Preparation:**
 
-I use 4 led's on each side. Solder the cables and add some heatshrink wrap the end. Probably a good idea to test and configure them first too, so you don't have to take it out again after you've mounted it.
+I use 9 led's on each side. Solder the cables. Now it's a good idea to test and configure the neopixels too, so you don't have to take it out again after you've mounted it, in case something is wrong.
+Just hang them over the spool holder and make sure nothing can short circuit while testing.
 
+**Mounting:**
 
-Mounting:
+- Guide the cables through the 1515 extrusion over the mid-panel.
+- Push one diffuser in. (Do this in the front with the led strip as far back as possible)
+- Slide the diffuser back while guiding the led strip through it. One by one.
+- When you get to the last diffuser on either side, you have to partially insert the strip into the diffuser. Then carefully try to bend/align it with the 1515 slot and carefully pop it into place. Having it all the way to the front gives you more leeway to bend without damaging the strip.
+- Do the same on the other side.
+- After you can wire them in parallel and connect them to the BTT SKR Mini E3 V2 neopixel slot.
 
-Push one in, then slide the led strip into it and keep things in the back. Then keep adding one and one until finished. Et voila. Slide the cable over the back panel and into the electronics bay. Wire them in parallel and put them into the BTT SKR Mini E3 V2 neopixel slot.
