the Absynthesis collection: Balancier by Big-E Assembly Instructions
The second item in my new Absynthesis collection: a fully 3D printed Balancier. Fully functional; An essential piece for any aspiring absintheur. Also a fun bit of engineering. The Balancier (or Brouilleur Auto Verseurs) was invented over a century ago to make the preparation of absinthe a no-brainer. Big-E's Absynthesis is a set of 3D printable absinthe accessories and bar-ware. Inspired by my love of absinthe and the Wormwood society - http://http://www.wormwoodsociety.org/ I hope you like this thing! I worked hard on it. Please make this for personal use or as a gift; Do not resell this design; General use is Creative Commons with citation.

Materials needed: A drill (a hand drill, manual or electric) with a 1/16" drill bit, a length of 1.75mm filament or a paperclip, and a tube of Super glue Optional: 1/16" hobby tubing (aluminum or copper), small needle nose pliers, a dremel tool with a cutoff emery disc and a small pick
Step 1: Print the parts You will need to print the following parts to assemble the Balancier: Balancier_cup_final.stl - print one copy at the highest quality you can; I suggest .1mm layer height, 2 shells and 20% infill. more shells and/or infill will result in a better part, but isn't required. Balancier_Leg-clip_helper.stl - print two copies Balancier_Leg-smooth_helper.stl - print two copies the legs should be printed at the same level of quality as the cup, however, at 100% infill, while it may take longer to print, will result in stronger legs. still, I used the same settings as my cup. break off the helper disks (and the support pin on the legs with the clip) when printing is complete Balancier_spoon_simple_smooth.stl - print one copy Print the spoon at the highest quality you can, at 100% infill Balancier_Timing_clip.stl - print two copies Balancier_Timing_clip_2.stl - print two copies Balancier_Timing_clip_3.st - print two copies you will need to print a set of timing clips, there are three different lengths available, depending on your assembly, one size may fit better than the others; I used the #2 clips in my build, I suggest you print two of each, and try them all to see which ones work best for your build during final assembly. Print these at 100% infill, in the highest quality possible, suggested .1mm layer height.

Alternatively, you may print Balancier_parts_plate.stl which will print all the leg pieces and the timing clips in a single run, however, if your print quality will vary between parts, it may be best to print them seperately.
Step 2: Prepare the cup the nozzle at the bottom of the cup should print correctly, however, on some machines, the nozzle will be distorted, or sealed shut upon completion of the print. I have taken great pains to try to minimize the chance of this happening, but if it is sealed, you need to take your drill, and using a 1/16" drill bit, carefully drill a hole, from the inside of the cup in the center of the bottom. You can chuck the bit deeply, to just allow a small amount of the bit to intrude into the cup, this will minimize the chance of drilling it incorrectly. The hole must be centered in the bottom of the cup. If the hole is not sealed during finalization of the print, use the 1/16" drill bit to ream it if you wish. Optional step take a short length of 1/16" hobby tubing (a segment about 5 or 6 mm long), and, using a pick, flare one end of the tube. using the same pick, press the tubing, flared end up, into the hole in the bottom of the cup. this will help regulate and fine-tune the stream of water going into the spoon. While not required, this extra step will improve the performance of your finished balaicier. The tubing, if flared correctly, should stay put and not fall out.
Step 3: assembly Set the cup upside-down down on a work surface. Take the four legs, and insert the rectangular peg-end on each of them into a socket. they should alternate, in other words, a clipped leg should have a smooth leg on it's opposite side. see the image below for reference:

When assembled, an axle or pin placed in the holes on the clips should be directly under the hole in the nozzle at the bottom of the cup. in fact, using a needle, or a length of a paperclip in the clips while gluing them in place will help align them when gluing them in. Test fit the legs, and once you get them aligned, you can put a drop or two of super glue in each of the sockets on the underside of the cup, and glue them in.
Preparing the spoon: using the drill and your 1/16" drill bit, ream the axle hole in the center-bottom of the spoon part. center the spoon between the clips, and using either a piece of paperclip or two pieces of filament, make an axle. the filament will be a press fit: insert the filament into the hole on one side of the spoon, and, while twisting, push it in as far as you can. do the same on the other side of the spoon. it is easier to have the spoon between the clips on the legs, and insert through the leg clip, then into the spoon's hole. you can then slide the spoon to either side, and clip the excess. ensure the axle is long enough that the spoon will not fall out. a straightened paperclip will also make a suitable axle, but I used filament to make mine; It seems to work perfectly. You may need to trim/file/sand excess plastic from the top of the paddle in the center of the spoon if it is distorted by your hot end. refer to the model file to get an idea of how it should look . Add the timing clips: clip a pair of legs into a timing clip. try the different clips and see what works best (I suggest the #2 clips) install them with the center tie-rods beveled-side up. Slide them from the bottom-up, 4
until they make contact with the clip on the leg, so the bar is under one end of the spoon. the bar must butt up against the leg clip for this to work, otherwise, the spoon may tip too far, and the balancier will not work properly. See the image below:
If the clips don't stay you can either secure them with a drop of glue, or , heat the ends with a lighter or match, and squeeze them a little tighter prior to installation. If you are stuck, refer to the Balancier_Assembly_model.stl file for reference. Everything except for the timing clip placement is fairly accurate, and should help you immensely. Enjoy your Balancier! Please drink responsibly!
