This is a versatile, parametric tube holder designed to securely hold the milk frothing tube of the Siemens EQ.6 espresso machine, but adaptable for many other uses. The inner diameter is set to 6.95 mm with a 0.1 mm clearance, making it ideal for snug but smooth tube insertion and removal.
The design features an embedded slot for a 6x2 mm magnet (you should pause your print to insert the magnet), allowing the holder to be conveniently attached to any metal surface—perfect for keeping your coffee setup tidy.
The holder is fully parametric, so you can easily adjust dimensions like tube diameter, base size, or magnet clearance to suit other applications or devices.
✅ Designed with a 115° opening angle for ease of use
✅ Clean, minimal aesthetic
✅ No supports needed
Print settings:
I printed mine using PLA with a 0.8 mm nozzle for strength, accuracy, and faster print time.
