Vỏ hộp Heltec V3 dùng 2 pin 18650

This is a case for Heltec V3 that fits 2x 18650 batteries, this gives a good battery life of about 3 days and probably longer with sleeping.

Non printed parts 

4x M3?? bolts of various sizes - I can't actually recall what size 
 

The Good

• It can be painted to look like camo, cool!
• It takes 2x 18650 battery clips which means it works with flat top and button top batteries
• It might work without hot glue

The Bad

• I made this some time ago and my memory is vague on all the details you'll probably need
• It probably needs hot glue
• The bolt length is odd so when tightened they're too long and stick out, too short and they wont reach the nut
• The buttons pretty much require a resin printer but it might work with some careful sanding
• Its not waterproof despite the misleading gasket, just thought it looked cool
• Its a PITA to fit the antenna, you have to fit it first
• Be careful with the boards coax connector if you don't angle it correctly you're going to snap it off, there's a little channel to feed the feedline around so you don't strain it

The Ugly

• The solidworks file - Let me know if you have any issues with this and I'll spend the extra 20 minutes it was going to take to export it properly
