XNL 3D Pro GuardDog Enclosure (Ender 3 Frame Compatible)

Please note:
This is a legacy download which is intended for a very specific group of users, and you most likely don’t need this download 😉

I did decided to make this legacy download available for others though, because I thought it might be useful for other ‘heavy modders’ of their Ender 3 (V1)’s

Please do note that there is absolutely no support or whatever on or for this project/download!

Please also make sure to read the description bellow before downloading it.

This is the XNL 3D Pro GuardDog Enclosure (intended for the Ender 3 V1 frame), which houses all the additional and custom hardware for the XNL 3D Pro Printers.

This includes for example the USB HUB, additional voltage regulator(s), the XNL 3D Pro GuardDog itself (the custom relay, light, fire protection and temperature control board) and some other additional hardware which is printer specific per build.

The included spacers can (and should) be used to mount your own custom XNL 3D Pro GuardDog PCB inside the enclosure by drilling holes into the enclosure which match your (custom) PCB.

For the enclosure itself you should drill a hole in back wall and the left side wall (which matches with the rail of the frame itself) so that you could use the standard screws and ‘rail nuts’ to install it onto the frame.

On the left side of the enclosure there are two ‘indents’, this is for the XNL 3D Pro Printers which have an additional (either 12V or 5V) power brick tie-wrapped to it on the side for example.

Obviously most regular users won’t need this enclosure at all, but there are still quite a few whom are using the XNL 3D Pro (including quite a few on our own team also). Which is why I decided to also re-release this enclosure on the new public platform of XNL Future Technologies.

IF you are unsure if you need this, and how you would need to install this, then you probably don’t have an XNL 3D Pro and then you don’t need these files either, don’t worry 😉

Additional 3D Printing tip:
DO NOT print these enclosures in PLA! Simply because the heat of the board, or other components and the heatbed COULD potentially affect the enclosure if you do so!

IMPORTANT TIP: If you're planning to redistribute this project/product or if you are planning to use it for any commercial purpose (if the license permits these uses of course), then it is highly recommended that you 'copy-paste' this License and store it along with your download(s) for future reference.



Do note that all sections/'chapters' bellow constitute the entire license and that they are 'interconnected'. This for example means that if there is a section about Closed Source/Binaries License, that this doesn't mean that the rest of the license doesn't to those binaries. It just means that that section is specifically aimed at those files, while the rest of the license (where applicable) is also 'in effect' for those binaries.

Commercial Use Not Allowed

Commercial use of this project, product, the files, portions of it or the provided download(s) is not allowed.
This basically means that you can't use anything from this project, product, download(s) etc for commercial use.

Please note that 'Commercial Use Not allowed' does not only mean that you can't (re-)sell it, It basically means that you can't use this project, product, the files, portions of it or the provided download(s) for any commercial use and/or any financial gain.
Some other examples of commercial use which are not allowed are:

  • Using (parts of) the project, product, the files, code etc in or for your own work(s) which you intend to sell.
  • Using (parts of) the project, product, the files, code etc in your business so that you generate income by 'just using' the 'product' but not selling it or portions of it.
    A simple example of this would be: You downloaded a "calculator app" from our website which has the 'No Commercial Use Clause', but you are using that 'calculator app' to actually calculate prices and tax rates for your store. This would then basically turn this 'calculator app' into a "business tool" for your business, even though you are not selling the 'calculator app', you are still using it for commercial purposes which isn't allowed with this license limitation.

Because we think that the "Standard No Commercial Use Allowed Clause" can be a bit vague or even a pitfall in some cases, we've decided to exclude certain situations from our 'Commercial Use Not Allowed Clause',  hoping that it will be a bit easier for people to understand what they can and can't do with the projects, products, files, models etc which are tied to our "Commercial Use Not Allowed Clause"

Excluded from this "Commercial Use Not Allowed" clause are:

  • Using, showing, demonstrating, educating with etc this project, product, the files, portions of it or the provided download(s) in vlogs or in/on blogs (which in most cases could actually be considered commercial use).
  • If this project/product is for example a 'software package/suite', you are allowed to install it for customers (upon their request) and charge your own 'installation fee' for this (because you are charging for your time/service). You are however not allowed to offer a special installation service for this project/product specifically on your website or to your customers, neither are you allowed to actually charge your customers for this project, product, the files, portions of it or the provided download(s).
  • If this project/product is for example a '3D Statue/model' and someone asks you to print it for them, you are allowed to print it and charge your customer for the material(s), power consumption and your time. You are however not allowed to specifically charge your customer for this particular model or offer this model as 'printable product' (either on it's own or as a 'model package').
  • In case of a Printable 3D Statue/Model you are also allowed to charge customers for your time, paint and 'artistic work' if you are requested to paint it for one of your customers. Keyword here is: Requested. You are for example not allowed to offer this model/statue in your store as 'order this model painted as you like'.


No Redistribution Allowed

It is not allowed to redistribute this project, product or the files included in the download(s) in any way (either altered or unaltered). This means that you are not allowed to share or (re-)upload any of the files which you can download from this project, product, tutorial etc.

If other portions of this license state that you can use/redistribute certain parts of this download (for example: snippets, examples from a source code, or specific files etc), then those specific 'items' are exempt from the 'No Redistribution Allowed' rule.

If you need to make this project, product or files available to others (for example visitors of your blog), then you should provide them with a direct link to this page instead of 're-uploading' them to your own blog/website for example.

No Derivatives, Remixes or Modifications allowed

It is not allowed to release (publish, share or otherwise) derivatives, 'remixes' or modified versions of this project, product, it's files and/or download(s).

This means that you are not allowed to release, share or publish modified, altered, translated, reformatted or 'remixed' versions of this project, product, it's files or download(s). The 'No Derivatives' also means that you are also not allowed to release, share or publish (own) work(s) which are based on this project, product, it's files or it's download(s), and it also means that you aren't allowed to publish (own) work(s) in which you have 'included'/'incorporated' this project, product, it's files or download(s) (this also applies if you 'only used a small/tiny portion' of our original work(s)).

You are however allowed to make derivatives or make modifications to our projects, products, models, images, files etc which have this clause in their license if it's only for your own personal use, given that you do not publish (or otherwise) share the modified files or works, and that it doesn't involve illegal or license invalidating practices like for example (but not limited to): Circumventing (software) license (key) activation, activating (often software) portions for which you don't own a valid license (key), circumventing copy or copyright protection(s) and more of the alike.

Extra note in regards to the fact that derivatives and thus 'modified works' are allowed for personal use
We do also consider it within 'personal use' if you for example would download a 3D model made by one of us which has the No Derivatives Clause in it's license, and you would then make a derivatives works of it as a personal gift for someone like for example your mother, friend etc. However do keep in mind when doing so, that you or your friend could be held responsible if the personal friend you gifted this item to, decides to use it for commercial purposes (which would obviously still not be allowed, because 'gifting something with a license on it, doesn't invalidate the license!).

Our No Derivatives Licenses clause does not automatically gives you permission to redistribute the 'unaltered works', to know if you are allowed to redistribute the unaltered project, product, files, work(s), download(s) etc tied to this license (clause), you should consult/read the rest of the license for this project, product, file(s) or download(s). If the (rest of the) license permits redistribution, then this would mean (due to this clause) that you can only do so in unaltered (original) form and format.
