Designed for the Yocan Uni-Pro and has storage for cartridges. The reasoning behind this model is to be able to charge your device with the cartridge outside of it.

In the past charging my other devices has led to the cartridge heating up and even leaking into the mouthpiece in extreme cases. This allows you to put your 0.5-1G cart in one of the 4 .510 holes provided, maintain an upright position, and charge your device in the next bay over.

After a few designs I created this one which provides tilt support in all directions other than the front. This means that you can tilt the device back or to the side without it falling, but can easily remove it by lifting straight up or towards the front of the device.

The charger hole has been designed in and will accommodate most type-c chargers.

I printed mine in PLA but any filament (maybe not TPU?) should work.

UPDATE: Both files will work, I have added a tighter file to prevent the device from tipping out of the front as shown in the video. This means you must lift directly up on the device to remove it. Again both files function but I have added a tighter one for personal preference.
