So the goal is to create a side loaded attachment on a mod for dry herbs like the Tubo Evic. It emphasizes on a compact form factor to be used in a country where cannabis is illegal. I have made quick 3d models for an evic VTC mini. Would appreciate the help by getting early feedback on the design and heating elements that could be used for this (maybe something like the 'the project'?). Finally, I would want it to be more battery efficient than the Tubo, even if it means a smaller bowl or longer heat up time. Before looking at the images, just want to make clear this was a quick model so i didn't go into too much details. Just enough to show how I see it in my head. Evic VTC mini inserted into the sleeve. Sectioned view of the sleeve. Colored tubes are glass. Yellow = air pathway + mouthpiece Green = bowl (maybe can be made in SS for hybrid type vape?) Red = Glass chamber for the heating element Wires will crawl from the bottom of the heating element up to the 510 connection on the evic via the grooves in the walls. Dimensions of the model in the picture (sleeve + VTC mini) is 8.6cm x 6.2 x 2.8 Again, nothing final specially on the glass tubes and how they will fit in the body and with the other glass parts. Overall design and dimensions will change as I try to look for a custom glass maker or possible glass tubes that can be re-purposed for this project (hope someone would inform me on glass type, all i know is borosilicate glass is the standard) Planning to have the body be CNC machined from wood or possibly have it 3D printed in whatever available material that can withstand the heat the glass tubes will be reaching. Or made by hand haha I have a VTC mini on its way and will play around with some coils or try to recreate the coil the tubo uses. Also I have no clue on the firmware side of things of the mod and would be glad to learn more about what I'm going to need. Thank you!
