Compustar T13 Fob case.

I have some thoughts for you that are coming from a “trying to be helpful” place.

The use of self tapping screws concern me. I’m wondering how many times you can install/remove those screws before the holes become unusable. Have you thought about using a nut on the backside but the nut is inside a counterbored hexagon hole so the edges of the hexagon hole are the wrenching/backing feature? This should allow for multiple installs/removals without messing up the holes. I have used this in the past with 3D printed plastic pieces and it seemed to work well. In your case, I’m just not sure if that would work or not due to the geometry, etc.

Once the holes are tapped the threads are there. There isn’t any reason to take them in and out. Its a self contained unit that requires no servicing.

In theory, agreed, however, stuff happens. In this scenario, is the end user expected to install the self-tappers the first time or will it come assembled and then the user has to disassemble to put their fob inside? Tiny self-tapping screws bother me, especially in 3D printed plastic.

I have considered it. The current screws are less than ideal. I'm waiting for a different screw from McMaster-Carr at the moment. Trying to see how well they work as a thread forming screw. I've taken mine apart a few time to test it and the screws I have now are a bit short so they're not ideal. I'm also considering using an internal print and place nut or a heated thread insert. But they will make it considerably bulkier. I know cased like AJT use a longer m4 screw I believe in their injection molded parts. I have a few of their cases for my 4runner previously and both of my Rams. They are great cases. They use a PC-ABS material per their site. This is Carbon Fiber ABS and has held up quite well to be throwing it around but thread integrity is a current concern. Ill be trying a few other methods and will report back for sure.
 
I'm going to get a few more filaments in colors similar to our trucks options. As well as others if need be. I'm gauging interest and price on these. Generous friends have suggested a nice number but curious what y'all think would be fair.
I think those friends should offer you at least $250!

Now, as for me…I’m not your friend…so, how’s $27.96 sound? 😜

$25-$30 would seem reasonable. That's how much I'd be willing to spend.
 
2 Fer $50 save on Shipping :)... there used to be this suit or shirt salesman here and it was always "Two Fer something $$$"
 
I’d be in for a plain one! Just tell me how
 
Any progress on these? I ordered that dumb little case on eBay, only to have TWO different sellers send me the exact same WRONG case!! Obviously, the sellers are one in the same idiots in China!
 
I did get some heat set inserts and out them in the one ive been carrying around. Making sure they hold up. So far so good. Ill post up what those look like tonight.
 
I'd buy one, keep us up to date when you're ready to start selling them 👌
 
put me down for one as well carbon fiber one
 
Sorry Fellas, I got wrecked by covid this week. Ended up leaving work at lunch on Tuesday. I really only check the forums when I'm bored at work so I haven't been on lol. Going to get a few of these printed up for yall so we can get this going ill let you know once I have them ready to ship.
