Simple Lampshade

thingiverse

Simple lampshade that can easily be modified by adjusting the two sketches in FreeCad that form the basis for this project according to your own needs. The way it is supposed to work is by wedging the clamping ring into the base of the lampshade, where it clamps tightly onto a cylinder due to the friction of the printing lines. There is some wiggle room, but measuring twice and trying test rings first may be advisable before committing to the full print. My mother recently bought this medusa hair type lamp without any shades, prompting my father to express his dislike for having to look straight into the lightbulbs. I decided that this might be a nice reason to learn some FreeCad, making it my first ever attempt at any CAD software, even coming from oldschool Blender where I found the learning curve steep. If you change the height and width radically, don't forget to adjust the radius of the pipe and its curve for the cooling holes. The current airhole diameter and curve are adjusted so that there is no possible way or angle through which you can see the lightbulb, as per my father's explicit wishes. The current wall thickness are specifically designed for 2 walls of 0.8 linewidth, which results in a print time of about 4 hours even at 30 to 40mm/s.
