ModuRamp – Modular Threshold Ramp Robot Vacuum Cleaner

🧩 Modular Threshold Ramp – Robot vacuum cleaners & co. overcome any doorway! Individually adaptable • Expandable • Stable thanks to dovetail system

Does your robot constantly get stuck on door thresholds? End that now! This modular threshold ramp is the smart, 3D-printable solution for all height differences in your home – whether 10 mm, 20 mm, or 30 mm high.

Perfect for:

• Robot vacuum cleaners (Roborock, Ecovacs, Dreame, Xiaomi etc.)
• Workshop carts, rolling containers, furniture dollies
• Strollers, rollators, or small robots

You build exactly the ramp you need – in length, width, and height. No more compromises!

Why this model is an absolute must-have:

• Fully modular – Building block system consisting of a left end piece + any number of middle pieces + a right end piece
• Ingenious dovetail system – simply slide together, rock-solid and seamless
• Freely scalable – from 20 cm to over 1 meter in length, any width by placing multiple ramps side by side
• Super stable – 3–4 walls + 20–40 % infill is perfectly sufficient
• No gluing required (optional for permanent installation)
• Parametric in Fusion 360 – adjust height, length, and angle yourself

See the assembly live in the video – the finished ramp is ready in just a few seconds!

Prototype photos: The green test parts have a height of 17 mm and a width of ~56.6 mm – perfect as a reference for your own customization.

🛠️ Step-by-step instructions (with schematic explanations)

1. Take measurements Measure your threshold:

• Height (e.g., 17–30 mm)
• Desired total length of the ramp (the longer = shallower incline → better for robots)
• Width (e.g., 60 mm per track or multiple tracks side by side)

Tip: Rule of thumb = ramp at least 3–4 times as long as it is high → super gentle transition.

2. Plan parts The system consists of three types:

• Left end piece (with rounded entry ramp)
• Middle piece (repeat as often as desired)
• Right end piece (with rounded exit ramp)

Examples:

• Bambu Lab A1 (256 mm bed): 1× left + 2× middle + 1× right = approx. 1 meter ramp
• Bambu Lab A1 Mini (180 mm bed): 1× left + 4× middle + 1× right = approx. 1.08 meters

3. Print Recommended settings:

• Material: PLA or PETG (PETG for higher load)
• Layer thickness: 0.2 mm
• Infill: 20–40 %
• Walls: 3–4
• Print orientation: flat on the bottom (no supports needed!)
• Print bed: normal, no adhesive needed

4. Assembly (see video) Simply slide the parts together using the dovetail profile – done! The connection is so firm that nothing wobbles.

5. Fine-tuning

• Too steep? Just print one or two more middle pieces.
• Too narrow? Just place several ramps parallel.
• Adjust height? In the provided Fusion 360 file, simply change the “Height” parameter.
• Dovetail in wrong position → simply change in customization mode

6. Optional: Permanent fixation A drop of super glue or hot glue into the dovetail joint – holds forever.
