Vase mode tessellating crystal, now with snap fit LED base

The crystals can be printed in pairs (normal + mirrored) for best tessellation results. You can print them as solid objects or as translucent hollow objects when printed in vase mode.

One hollow vase mode crystal needs just 90cm of filament, so it's a perfect object for those last meters of filament everyone always ends up with… See included .gcode files for the normal and the mirrored variants. 

It's best to print sets of both variants, so you can make many awesome tessellating patterns. Warning: making patterns is very addictive and it will make you want to print many more crystals! Luckily one 1 KG spool of Prusament will be plenty for about 380 crystals! That's only 8 days of non-stop crystal printing.. I think I need a print farm! 8-D

Add some LEDs for more awesomeness, especially when using translucent materials! See the LED base update below!

Print specs I used for my MK3S+:

Vase mode crystals: Prusament PETG clear, textured steel sheet, 250 degrees nozzle temp, 90 degrees bed temp, 0.15mm layer height, 0.4mm nozzle. 4 bottom layers, vase mode. Print time is about 28 minutes.

LED base: Prusament PETG galaxy black, textured steel sheet, 250 degrees nozzle temp, 90 degrees bed temp, 0.2mm layer height, 0.4mm nozzle. 4 bottom layers, 3 perimeters to increase bottom layer adhesion for small features. Print time is about 1 hour and 9 minutes.

Feedback welcome!

Consider this a work-in-progress project while I'm learning Fusion 360. Any feedback or requests are welcome and I'd love to see makes in other colors or remixes for other types of LED's, etc. My hacked together F3D file is now attached too!

Update 1 - 2022-12-31 - now with LED base:
Crystals are always better when illuminated, so I decided to make a quick and dirty snap-fit LED base for a CR2032 battery and a Piranha/SuperFlux LED that I had on hand. No fasteners, no soldering required, no current limiting resistor necessary, but there's no power switch (yet…). The base can also be mirrored, just like the crystals. It doesn't affect the installation of the LED and battery.

The CR2032 battery is very common and can be ordered at many webshops. Or you can harvest them from old PC motherboards, since they're used as BIOS battery to keep time.

The SuperFlux / Piranha leds can be ordered from various electronics suppliers and webshops such as Reichelt or Amazon.

The base consists of 2 snap together halves, to make it easy to install the LED and the battery inside. The top half of the base uses minimal support material for 3 small cavities. I've tweaked the slicer settings so it's easy to pull out the supports in 1 piece. See included .3MF or .gcode files.

The cathode leads of the Piranha LED must be bent outward 90 degrees, so they touch the top side of the battery (negative). The edge and bottom of the battery are positive, so both anode leads must touch it. Below is the most common pin configuration of these LEDs, but make sure to check the datasheet of your supplier, just to be sure..
