Crazy Radio Sleeve w/ LED hole
I loveeee the original model. I tried a few other versions but this was by far the best. It is the slimmest, requires no additional hardware, and is very nicely designed. However I did want to see the LEDs, I saw some others posted makes in transparent/translucent material which allowed seeing the LEDs through the case which I thought was a great solution (and I love transparent electronics), so I printed it in resin. I found out that the inaccuracies in my FDM printer actually held the board securely in the sleeve, but when printing in resin where the dimensions were more true, the case slid back and forth a bit. This wasn't a huge issue but I noticed another commenter had posted about this small annoyance as well. So I did 2 things:
1) I added a hole to view the LEDs through
- I also added an optional led diffuser [led_diffuser2_buldge&bottomBevel] to pipe the light up into a nice retro style light. This looks very seamless and cool imo. It has a slight bulge at the top to help it stay securely in place. I also added a fillet to the bottom of it to help reduce elephants footing on my resin printer that made it a bit difficult to insert into the hole. It is quite a snug fit with only .1 mm of tolerance (because I printed it in clear resin and my resin printer is very accurate). If the elephant's foot is an issue, simply take a razor knife or file to trim down the edges and with a little bit of work it should snugly slip in.If it is too big all around, scale it down slightly in the x & y direction in your slicer. Some notes about putting the diffuser in: The LED hole is slightly on the bevel of the case, so I modeled the slope into the diffuser as well. For best fit and finish, take notice of the small slope on the top and line it up correctly with the slope on the case. When inserting it, I first used pliers which ended up slightly tearing up the finish, and would allow the possibility of over inserting it. To fix this, I suggest getting it started in the hole, then flipping it upside down so the diffuser is on a hard flat surface (like a countertop), and pushing the case onto it. This will prevent any possibility of over insertion and create a perfectly flush top to the case.
2) I added a few mm extra length to the back of the case [Radio_Sleeve_wHole_bigBack], allowing the antenna to sit flush against it and prevent any wiggling back and forth. If your antenna is no longer at the proper angle to fold straight up, simply hold the adjustment knob and turn the antenna until it is properly aligned straight up and down again
3) There is also a no-hole model [Radio_Sleeve_v2_nohole[resin]] for any transparent prints which dont need the LED hole. It still has the extra few mm added to the back so the antenna can prevent the case from sliding around
Big thanks to the original creator of this model - it is expertly designed!!
