Simple tube case for Heltec Wireless Stick Lite V3 Meshtastic node

This is a very simple case for the Heltec Wireless Stick V3. It has an N-type antenna mount on top and an M12 cable gland for USB power on the bottom. Since this is a stationary node, there is no battery inside. The case consists of three parts, an outer sleeve, an inner insert that holds the Heltec and slides into the sleeve, and a cap that screws onto the bottom of the sleeve. Assembly should be pretty self-explanatory. There's also files for a 1.5inch and 2inch pole mounts. TBH these mounts suck, you're better off with a hose clamp or maybe a few zip ties, but I needed to get the radio at least a few inches away from the pole for it to fit thanks to another antenna I already had mounted on the pole.The antenna mount uses four M3x4.5x6mm heat set inserts and four M3x6mm countersunk machine screws. These are the only fasteners needed for the enclosure. I printed it in carbon fiber PETG with fuzzy skin on the outside of the sleeve. PETG is fairly UV stable and carbon fiber helps stabilize it more, but ASA would be a better choice. Note: the cable I used to power the device is some generic 18awg speaker wire with a USB-C connector soldered onto the end. I first passed the wire through the cable gland, then soldered the USB-C connector to it. I don't know of any USB cables that would be able to fit through the cable gland.
