Big C Crystal modular

thingiverse

A modular remake from Big Clive's Crystal. The spikes/crystals are printed in vase mode, with 4 bottom layers. 1.5h print time at 50mm/s and 0.2mm layer height. They can be scaled in Z axis to be taller or shorter. The base is difficult to print, it should be printed upside down to prevent using supports but it's angle is well over what is recommended. I managed to do it by printing innerwalls first but it wasn't fully success. Had to support it once with tape, luckily a lot is covered byt the crystals and in clear filament it is hard to notice such flaws. I used 0.2mm layer height, probably it should be printed with 0.12mm. Printing the base takes about 3.5h at 0.2mm and 50mm/s if you can do it without supports. If you decide to scale it in XY, you have to think about the led holes, they are now 5.5mm diameter. For wiring diagram (i have no affiliation with the channel): https://www.youtube.com/watch?v=orOaQHuhr2g&t=560s My version uses slow color changing RBG LEDs, max 3.2V, 0.2mA. Series resistor is 40ohm, it drives them max (or a bit above max actually) with 5V power supply. It is too bright for my bedroom so you can use larger resistor. I used "memory wire" for the internal wiring, feel free to make your own hidden art the way you like it ;)
