*** Update. After testing different switches, I've discovered that there is quite a lot of variation in switch dimensions. Therefor, I have uploaded another profile with a looser fit for the switch. If you're having problems with fitment, please use this one.

The "missing P1S button"…

Yes, that's right, all of you proud owners of a P1S have it in your heart, there SHOULD have been a push button switch in the front cover where that ugly oval hole exists :)
Well, if Bambu Lab "forgot" it, shouldn't we print something and be able to add one?
As far as I know, this is the first attempt for a functional cover of that hole.
This was designed for the P1S, but maybe it could work on the P1P as well. It purely depends on the molds of the "front cover". I'm pretty sure (and hope) they are all the same for all of the P1S out there, maybe they are similar for the P1P. I'll be waiting for some feedback from P1P owners and update this description [Update: Judging from the pictures of antonjoohansson in the comments, we can see he installed it on his P1P. So most definitely, it should work on a P1P].

I have uploaded a zip file with the instructions in the "Raw Model Files" section.

Q&A:

• Who is this mod for?
  For anyone who wants to control anything with a push button switch, in a convenient place in front of the printer. Most popular would be a LED switch, a power switch for an external camera, but a main power switch could be possible too.

• Do I have to buy something?
  Yes. Just the push button switch. They are dirt cheap and you can find them everywhere. Just take a look at the the following links (no affiliates) as a reference and search for anything that is visually identical:

• Is there any reason you chose this particular switch?
  This was the one I found laying around in my electronics' drawer ;)

• Will I need anything to keep it in place like screws, glue, double-sided tape or something?
  No, nothing. The switch "holder" is designed to have a very tight fit between the metal frame and the front cover, which ensures that it will stay there for countless hours of printing.

• Is there any disassembly required?
  Yes, but just the minimum. 3 screws and then removing the front cover. You can follow the procedure in the video from Bambu's official wiki for the P1P, it's literally the same for the P1S.

  Please review the video from the beginning until 00:47, the final assembly will be the same in reverse order.

• Hey man, I'm having some trouble installing your print, everything is so tight. Can you provide something more loose?
  No! It was designed to be tight, in order to stay in place and not move around. If you put patience and clear thinking, you can get it to fit. Maybe you'll have some tough time to put it in place once, but afterwards it will stay put forever. [Update: I found out that visually identical switches have slightly different dimensions. So yes, I'm now including an additional profile with less tight fit.]

• Can I use this switch to re-route my printer's main switch in the front for convenience?
  Perhaps, but don't take my word for it. After some small research, this switch is supposedly rated for 1A/240V. My European model P1S did not exceed at any time 200W during printing (ASA, 270 Celsius nozzle, 100 bed), so theoretically it could.
  But if you ask me, to be on the safe side, NO! Whatever you decide to control with it, YOU are fully responsible and accountable for. Test with caution.

• So, how do I have to wire this switch?
  If you are not familiar with a multimeter and a soldering iron, then this print is not for you. If you are, then you know how to do it.

• Great idea man. But what about us X1C owners?
  Eat our dust X1C owners! Just kidding, after all, we are all part of the same happy family :) There are no empty holes on the front cover as I'm aware of on the X1C, so nothing to implement by my side :'(

• I like it. How can I help?
  Just comment and rate for the print. Any positive review will be highly appreciated. On the other hand, if you are having problems, just make a comment about it and I'll try to help.
  Thank you.
