Chụp đèn trần lắp trục trung tâm

This lampshade is for central mounted ceiling lamps.
it consists of 3 identical parts that is then screwed together with m2 nuts and bolts.
I printed mine out of transparent PCTG and treated it with a spray on clear coat. 

the parts are not easy to print and you need to place them on one seam and then add support along the other seam to prevent it from falling over see the image i posted, i added a 3mf file that worked for me with the supports. 

if you want another pattern you could take the untextured lampshade and put it into bumpmesh https://bumpmesh.com/ and experiment to your hearts content.
