This is a wall mount system for the Yama CDM8 cold drip coffee tower. It is not necessary to purchase the entire CDM8 (also called 6-8 cup), it is sufficient to purchase the replacements of top, middle, and bottom beakers, as well as the brass fitting, ceramic filter, and (optionally) the glass coil. I've seen them on both amazon.com and espressoparts.com, though if you're in Europe you will probably have a different retailer. It should come out to about $170, and the printed parts should cost $5-$10 depending on the cost of your filament.
additional parts needed:
(optional) Gorilla/VHB tape
number 6 x 3/4" wood screws, you will need 6 screws, as well as anchors if you are mounting into drywall. Anchor bolts are also an option, as long as the outer diameter of the threads is 4mm or smaller and the head is 8mm or smaller, the holes will work.
I installed these with VHB tape on the back and then screwed into some wood paneling. The VHB tape helps keep some pressure on the part, and helps stick the part to the wall while installing.
I installed the parts relative to one another, they don't have to be perfectly level or aligned, so long as the drips fall into the next container.
Printed in PETG with 0.25 layer heights. Ensure proper layer adhesion, print the large flat side down (same way the parts would mount on the wall, as in the pictures). Gyroid infill is preferable.
Sanding is not required, but can help remove any burrs or blobs that might cause the glass to not seat evenly along the rings.
Place a small piece of Gorilla or VHB tape on the back of the part, then install with #6 (4mm or smaller outer diameter on threads) wood screws, half inch or 3/4 inch should work well, though I used 1 inch screws.
The design was made in Fusion 360. The parts were designed to be printed as oriented when in use, and should already be arranged in this manner (unless your slicer has z/y swapped). The bottom and top parts should be printed with a fairly high infill if you don't want deflection when the parts are loaded with water, which will add 2lbs or about 1kg of weight.
The bottom part was designed with a 45 degree slope so that it could be printed without supports.
