better ELRS DIY JR module base

<p>This is a remix of the official ExpressLRS JR module bay.</p><p>I noticed that the official one didn't fully lock into the JR module slot, and after a bit of tinkering I found out that the little clip is way too long, and doesn't engage with the slot.</p><p>I took some measurements, and cut it up to size. It's a bit smaller than the clips on non-DIY modules (such as the crossfire module I have), to allow for 3D printer tolerances.</p><p>Speaking of them, I also scaled the whole model up a bit as the original was way too loose, now it's pretty much spot on but you can scale it down a bit if you feel that it's just a bit too tight for you.</p><p>I don't know if it was a problem only with the Radiomaster TX16S, but it now is compatible with it. Enjoy!</p><p>I originally printed it in PETG because the bays printed in PLA warped after some time from the constant force exerted by the clips, but now it should be fine (if not better, as it's more rigid) to use PLA too.</p>
