This is my first big project involving more than 2 simple parts, with some electronics added as well. From design, prototyping to final product, it took me nearly one month. A lot of mistakes were made, a lot of filament wasted, but it's still a very special feeling to see your own creation coming to life, and after so much work I wanted to share the model in case some other people wanted to give it a try, so here it is.
The design itself has been heavily inspired from some promotional renders Intel used for their Arc GPUs.
Materials and Print Profiles
I used PolyTerra PLA for the black parts, which has a matte finish that kind of smooth the appearance of layers (they show up way more in pictures than in real life for some reason). I also used transparent PETG. (Transparent PLA would most likely work just as well). All of this is printed at 0.2mm layer thickness with the default profiles from Prusa Slicer 2.5 for my Ender 3, except for the two posts where I used 4 walls instead of 3.
For the top half of the base (file "3.Base Top Half"), you want to print it in the correct orientation which will unfortunately result in a lot of supports under it.
Required Hardware
Other than the printed parts, here's the hardware required to assemble this :
For all screws, I recommend flat head/rounded top screws, or anything with a relatively thin head.
Assembly instructions
Electronics
For the Electronics I won't go into details on how to connect everything. There's a lot of information on the Internet about controlling Neopixels/WS281x LED strips with a Wemos D1, and they don't all say the same thing (some says to used a capacitor, others resistors, others both… some include the logic level converter, others do not…). I don't want to give bad info, so do your own reading, try your own circuit.
That said, here's he part I ended up using :
IMPORTANT NOTE FOR REGARDING THE CURRENT : With the LEDs I used, at full power the LEDs alone can use about 1100 mA. (I measured 31 mA per LEDs, x 35 LEDs) I enabled the current limiting functionnality of WLED with a limit of 800 mA (which keeps 150 mA for the Wemos, and leaves 650 mA for the LEDs.) Realistacally I could probably use a lower limit since I ended up setting the brightness to 25%.
Change log
2023-05-25 : Updated file “3.Base Top Half.stl” to fix a thin wall I noticed while assembling my stand. It shouldn't cause any issue at all if you already printed it. (The one I built isn't fixed)
The author marked this model as their own original creation.
