I just finished (i think) this enclosure for my spider and I’m hoping to move them soon as they just molted and the one they are in now is getting too small. The materials I used in this enclosure include quartz and opalite which I believe are non-toxic, some glass beads and plastic beads and other plastic items, the little tiles are stained glass, and silicone to hold everything together. The disco ball was also styrofoam on the inside so i did a thick coating of silicone to hopefully prevent it from getting gross or leaching anything. I think that’s everything? If you want to know where I got any of the materials I can send links. 

The enclosure itself is 3x3x6 for reference. I have a larger one I can move my spider to in the future if needed as well. 

FEEDBACK: 
Let me know if any of this looks unsafe, if any of this might cause problems with cleanliness, or if I should add anything. I am 100% open to advice and suggestions!!!! Thank you!!! 
is a hanging disco ball a bad idea? should i attach it to something so it doesn’t move and possibly break webs? 

It also has a sliding door on the front that is not on there in the video lol 

new enclosure! feedback please!
