Gridfinity Heltec Lora V3(Meshtastic) case (alpha)

Holds a Heltec Lora32 board and a battery. Does not include any outside access to any of the buttons.  

STEP files and permissive license provided.

Everything should print on almost any printer with no supports.  Things are rather carefully designed to avoid bridging.
 

This is an alpha release for one reason, the SMA connector can spin when overtightened, because it's designed to work with the washers in their usual places, which doesn't allow for the usual hex recess design. 

There is an alternate, untested version of the case. meant for use with the original battery plate, not V2, which has the hex recess.  You'll need to keep any SMA washers on the outside of the box, much like other designs.  For the brave beta testers only!
 

Supplies

• Blue tack or other poster putty
• A hot glue gun
• A lora32 with the SMA cable
• An optional battery

If using a large external antenna on a thick heavy coax, I suggest a short right-angle coax jumper in between, because the cables that come with fiberglass antennas can be incredibly stiff, making mounting a hassle,  and the springiness can unscrew the cable if not crazy tight.

Features
 

• Supports up to the 3000mAh MakerFocus battery or similar sized battery (66mm*33mm*10.5mm)
• Gridfinity stackable on top and bottom
• Lanyard hole near USB is large enough for paracord
• Groove on opposite side for paracord lashing

Assembly
 

1. Nothing on this should require any force or bending besides tightening the screw and inserting the filament pin.
2. There is no power switch or access to buttons. Disable transmitting before swapping antennas, and only use protected batteries.
    
3. Apply hot glue to the tiny coil antenna to protect it from getting broken off during assembly. Apply hot glue to strain relief the SMA side of the cable.
    
4. Insert the battery, if any, into the main body. Use some Blu-Tak to prevent any sliding around and cushion any drops.
    
5. Screw in the SMA connector to the housing.  Connect the other end of the cable to the board.
6. Cover the battery with the battery plate, the side with ridges facing up. The battery plate is also what keeps the SMA from spinning.  
7. It's just plastic, so be aware the brass can strip the plastic and spin. Probably not an issue with short antennas.  You might want to use a drop of super glue to attach the SMA to to case. 
8. You might also want to attach and fully tighten an external SMA right angle jumper, or the antenna you plan to use, while you still have access to both sides of the connector.
    
9. Insert the cable into the board holder and route the wire as shown.
    
10. Insert the spacer cage piece into the holes in the board holder.  Keep it all together using more blu-tak.
     
11. Put the board holder into the main body(You need to start an the non-USB-port side). Be sure the cable is mostly under the battery plate, not bunched up and causing stress (Perhaps the battery plate needs a remix?)
     
12. Use a piece of raw filament in the small side hole to hold the whole thing together.
