SwitchBot Curtain Ramp - For Extenable Curtain Rods

SwitchBot Curtain Ramp - For Extendable Curtain Rods

This allows the SwitchBot Curtain to move between extendable curtain rods with varying diameters without getting stuck.

Background

Let me start by saying that SwitchBot support is great, in my experience. They do offer free replacements for the ramps that come with the Curtain bots. However, shipping is not free and it costs $30 to ship it from China to USA. That is absurd and it is not their fault. Especially for a small piece of rubber (or metal depending on the version you bought).

Instead, why not just 3D print the ramp?

Parameters

This model is parameterized to make it easier for you to adapt it to your curtain rods. To change them, go to Modify → Change Parameters in the toolbar.

largest_outer_dia (default: 19.7 mm) This is diameter of the larger rod.

inner_dia (default: 16.38 mm) This is the diameter of the smallest curtain rod the bot needs to step up from.

min_thickness (default: 0.4 mm) Don't make a big bump for the bot. Keep it as small as possible. 0.4mm, being the size of my nozzle, seems to work fine.

ramp_length (default: 30 mm) How long you want the ramp to be. The greater difference between the rods, the longer the ramp.

smallest_outer_dia (calculated - do not edit directly) This is automatically calculated as inner_dia + (2 × min_thickness). It represents the narrowest outer diameter, ensuring the minimum wall thickness is always maintained. Adjust inner_dia or min_thickness to influence this value.

.f3d File Note

The f3d file is in the zip archive because of an issue uploading the file to Printables. See this link.

Requests

If you pinky-promise to give the model a Like, I will happily export an stl with your provided curtain rod dimensions :)

Other Notes

If it's too loose and moves around then using some tape might help. Either on the outside connecting the printed part and the larger rod or putting it on the smaller rod where the printed part will sit.
