Big Clive's Crystal

Have not printed it yet. Wall thickness is 0.8mm, check in your slicer that they all get at least two 0.4mm lines. Also check where it puts the supports, there should be quite minimal amount of them but at least Cura puts some in the crystal ends depending what orientation it happens to be. Those places should be printed as bridge, there is a wall at both ends.

Print time approx 20 hours at 50mm/s with 0.2mm layer height. It is quite large and a lot of time is spent on supports, not the easiest of prints.

This is the Big Clives Crystal or at least an attempt to it, edit: updated to be closer to the real thing.

See the instructions how to connect LEDs. I have no affiliation to his channel and this is NOT approved by him. https://www.youtube.com/watch?v=orOaQHuhr2g

Update: redone in Fusion360 for closer resemblance to the original. It is big so scale it to fit your build plate. The LED holes are 5.5mm, you may need to open them up a bit if you scale it down a lot.
