TruPortal - RFID Reader
So TruPortal is a company that makes access control systems. Some really nice hardware, unfortunately the dipshits at TruPortal have decided to abandon all of their customers and distributors. So they closed up shop. As of three days ago (Dec 20 2021) they no longer even have tech support in North America. Assholes.
The parts for their access control systems are only going to get harder and harder to find. To that end I am drawing the back plate and face plate for the RFID reader. this is something that gets abused alot and will need to be replaced regularly. For example I have a reader in an elevator I am going to replace today. The tenants for some reason like to smash the reader, I guess because they don't like being able to get to their floor? who knows.
Just one thing I do want to explain about the different files. You will notice the manufacturers version has one big hole in the middle. Mine has a small hole and a slit cut out of it going to the side and its much thicker. This is because the manufacturer required you to cut the wire to install the back plate. But the back plate breaks all the time, it and the cover are the two most commonly replaced items. My design does not need you to cut the wire to install the back plate and after some testing, this design change does not appear to introduce any real weakness. Its faster for the tech to be able to quickly install this way. The original design is made of ABS but its very thin and for some reason brittle.
I make this replacement out of PLA+
The design was done via onshape, a free online 3D modeling software that was created by the original developers of SolidWorks. Its great but the free account means all your files are available to anyone. As I dont care, this is not an issue.
This drawing was done with a basic 2D cad drawing done with cambam (my go to because its very simple) then imported in to onshape. But really you can do it all in onshape, I just like my way better.
To get you started, here is the real basics.
1: Select the plane you are going to work on.
2: Right click the highlighted plane and select "New Sketch"
3: on the top bar, select "dxf",
4: in the menu that comes up select import on the bottom and select your DXF file
5: now your object should appear, select extrude from the top bar to see an example of what you can do.
6: If that does not blow your mind, you are either experienced in this already or a generally boring person.
Now, there is a lot of work ahead, but it took me about 8 hours of mucking around on youtube to learn how to draw my first part, but that part was a hard drive adapter for a specific piece of equipment. It was simple yet complex. Its on this site and you can see it for yourself. since then the process has gone much faster, but I will say having a 3D printer has made it worth learning. Here is the onshape files that I made in the end:
UPDATE: These covers need work, they are close but not done yet:Cover: https://cad.onshape.com/documents/18c461b5c1f4de0debfb95c8/w/5725839a85b61110f81c58e1/e/f6fb0627c84b06ffb9ca2dc1
TESTED AND WORK GREAT! Backplate: https://cad.onshape.com/documents/beca8c37b89a7aaa1c020372/w/184ce3d5c3ab3b856062dd23/e/3fd8a0898e6b182e6e774f7b

And Now, Pictures:
I have since made a few variations to fit in odd places and in all instances the back plates hold up better then the factory units.
