Modular

The cupholder is modular and you can stack the module vertically as high as you want. To have a nice finish there is a top that you can optionally add. 

Installation

The system is not fixated by itself, and is meant to be fixed to a wall through the holes added in the back. M3.5 works like a charm. I recommend fixating the top and bottom most modules, and if you have a lot of them, add a screw every ~10 modules.

Printing

I have printed mine in Prusa Galaxy Black Prusament PLA. I used PrusaSlicer and made the gcodes on the 0.20mm SPEED setting with 10% infill. I used a I3 MK3S+ with a 0.4mm hardened steel nozzle.

Attribution

This model was made by FabriceVN over at cults3D.com. I liked the model and couldn't find a decent modular system on printables, and their license allowed for it to be shared with attribution.
