Anyone else have to resize the box? I just printed it and while it's a great design, it's 3x the size of the optocoupler.

Hey, thanks for the stl and the links to ebay, I just boght both the sensor and the octocoupler board for my ender 3 and I'll be printing the box soon.

No problem,I hope it goes well...i'm on all the main facebook 3d printing sites if you need any help. Best wishes. Paul

hey there, my optocoupler and sensor arrived today so I'll be installing them soon. Could you make the box longer so that my 24v optocoupler fits into it? it's 19x16mm, thanks

I've added some slots in the bolt holes to fit more frames

That's great. Thank you.

Nice Design. Would you be able to move the holes closer together in the one direction? I think you have them at 28mm. I need them to be 20mm for an Ender 3 Pro frame.

I've done a very quick edit to make slots in the screw fittings, that should do it. If not let me know and I'll re-model when i have chance.

Any chance we could get a version of the box with the wire openings on each end? The design is fantastic but seeing as the connectors are on opposite ends (length wise), the side slot seems a bit strange.

That is perfect, thank you! I will be printing that out today and using it for a guide I am writing, will be linking your design.

Hi...can you email me paulgawdan@yahoo.co.uk with this message, and if possible a sketch of what you mean about the T slot.. I'm happy to change some more things, just dont quite understand what you mean and only some if the message shows up on here .

Paul

Hi Paul,

I actually edited the message and removed the rest, I don't think it will be necessary. I am printing out the design and will be testing it this evening, will update if I have any more suggestions but as of now, it looks like it will work great :)

Hey thanks for this. I am total noob so can you share the connection diagram to the mainboard please. And last question is i need to flash a bootloader and install marlin in order to use this right? Thanks.

Here is a good diagram someone else did and posted here...
