Sm 2.0 DYI Case

Hi All,

I want to share my diy case i build. Wooden frame. Plexiglass and a wooden backplate. Used rubber draft band to make it dust and sound proof. Made the hinges myself in Fusion 360 and printed them on my SM A350. Made the hinges simply removable.

It’s a It has become a lot quieter. The only thing I’m considering is to replace the fan in the power supply for a silent version.

Now waiting for my orders from China. Ledstrip, Power unit, buttons for ledstrip. Esp32 camera to mount next to the printhead. And a fan for cooling the inside case.

Hope you like my setup :wink:.

Hi Stefix,

Thanks… What about the laser?

Your picture shows clear windows, there is no laserprotectionshield (I hope the orignal once were working) Only a note, the case looks cool!

You should be able to find a tint that will protect from the laser.
OR…These folks have a unique solution, using a small section of laser safety shield mounted right on the laser module…

Thanks for your info. I especialy choose clear Windows because of the light entering the room. So my case would not Block all light. Never thought about the laser light and blocking it in some sort of way. I think you see me in my office with the SM laser glasses on :joy::joy::joy:.

Your link to the website looks promosing.

Just get some cardboard or mdf or melamine panels that you can surround enclosure with. That’s what I do when working in garage around it even though I have amber acrylic.

So i added some stuff.

  1. ESP32-CAM with 160 degrees camera
  • mounted on the X-Axis. Used a servo to turn it left and right. Mainly placed to keep an eye on the printing.
  1. 3x ledstrip groups
  • (2x strips per group) (above, left and right).
  1. ESP32 microcontroller
  • Microcontroller for controlling the lights and sensors.
  1. DHT11
  • temp and humi sensor.
  1. 3 Buttons
  • Buttons to switch on the ledstrips.short press = lower brightness, longer press = higher brightness, long press = on/off.
  1. Home Assistant integration
  • to control it in my domotica system (smartphone included).
  1. 2x 12V 3510 FANS
  • to get some fresh air in and bad air out of the cabinet.
  1. 24V FAN replacement in the PSU
  • much less noise

Hope you like my setup.
Questions? Let me know!

That’s pretty nice work, I like how much features you added to your enclosure!

I’m currently also working on a DIY enclosure but one thing i haven’t thought of is to control brightness of the lights. Acutally a quite simple feature but thanks for reminding me of that anyway! :sweat_smile:

But one thing i don’t understand at the moment: is there a certain reason for choosing 3510 fans for air intake and exhaust? I’d guess bigger fans might perform better and may also be quieter… :thinking:
What are typical temperatures you get inside the enclosure while printing?

Thanks for replying :+1:.

I can’t show numbers for temp and humi yet. Made a mistake in wiring the dht11 :grimacing:. I feed it with 5v, but the esp32 has 3.3v ttl levels. So that won’t work. I gonna fix that today. With some fixing of the buttons (these have leds in them, two of them don’t work).

Good question about the 3510. First of all i choose a 12v version, because i had a mosfet left (i ordered for the ledstrips) , and with replacement in mind for a bigger version if necesary. But i made the fan because i can. I can’t tell you if fresh air is necesary. Maybee holding temp in the cabinet is better than cool it down.

Due to the hassio integration i simply can control the fans based on the temp or humi.

If it all works i share the temp and humi numbers during printing.

Hi All,

DHT11 is working now! Second button has a broken cable :frowning: .

@Andomaster , here are some number during printing:
Printing on Normal Quality using Luban.
Numbers during printing for 1 hour and 10 minutes. Without using fans in the cabinet.

hopefully you can do something with this data.

Hi SM friends :slight_smile: ,

I added another feature to my cabinet, a extendable drawer. Each container is 3d printed.


p.s. the pla is in the cabinet when I am not printing, since the cabinet is in the sun the pla can dry.

grtx,

Marcel
