TRI-SWEEP — 3-in-1 TPU Squeegee, Ice Scraper & Moisture Sweeper

TRI-SWEEP

Three cleaning tools. One print. No hardware.

TRI-SWEEP is a 260 mm equilateral cleaning tool printed entirely in TPU 95A. Each of its three edges performs a different task and can be identified by its engraved label and unique edge profile.

One grip for all three edges

The center of TRI-SWEEP features a raised circular grip pad with nine 20 mm finger holes arranged in an inverted triangular pattern.

One corner of the hole pattern points toward each working edge.

Whichever edge you place against the surface:

1. Insert four fingers through the far row of holes. This row is always parallel to the edge being used.

2. Place your thumb through the corner hole closest to the working edge.

3. Rest your palm flat against the solid center pad.

4. Push directly behind the active edge.

The grip works identically in all three orientations, so there is no incorrect way to hold it.

Your fingers pass completely through the tool instead of relying on a pinch grip. This provides secure control with wet hands, soapy hands, work gloves, or winter gloves.

Uses

TRI-SWEEP can be used for:

• Shower glass and bathroom floors

• Balcony or garage floors after washing

• Frosted car windows

• Window condensation

• Tent floors and camping mats

• Car floor mats

• Boat covers

• Standing water on smooth surfaces

• Light frost and thin ice

TPU is much less likely to damage glass, paint, tiles, or other delicate surfaces compared with rigid metal-edged tools.

Why TPU 95A?

TPU is not simply a material option for this design. Its flexibility is what makes the three working edges function correctly.

The WATER edge flexes like a proper squeegee blade and adapts to slightly uneven surfaces. The MIST edge provides a balance between flexibility and wiping pressure. The thicker ICE edge remains firm enough to remove frost and thin ice.

Scraping forces travel through the edge of the triangular plate, which is the part's stiffest direction. This makes the tool feel firm during use while remaining flexible and comfortable in the hand.

The finished part is also highly resistant to everyday abuse. It can handle being stepped on, stored in a car, exposed to freezing temperatures, or washed repeatedly.

Designed and verified parametrically

TRI-SWEEP was created using a geometry kernel with automated checks that run whenever the model is rebuilt.

The design verifies:

• Watertight manifold geometry

• Zero support-required surfaces

• Correct lip thickness on every working edge

• Closed-form strength calculations for every use orientation

• Worst-case loading under a 200 N push

• Safety factors between approximately 9 and 39, depending on the loading direction

The calculated worst-case stress is approximately 4 percent of the assumed strength capacity of TPU 95A.

A dimensioned 12-view technical sheet and a one-page usage and material document are included with the files.

Honest note about ice

TPU 95A is a flexible material.

The ICE edge works well for frost and thin layers of ice because your palm applies pressure directly behind the working edge. However, it will not outperform a rigid steel-edged scraper on thick, heavily frozen ice.

That is an intentional trade-off for having a tool that is flexible, safe around paint and glass, comfortable to hold, and printable as one single part.

Print Settings

Printer: Any FDM printer with a bed large enough for the model

A bed of approximately 250 × 220 mm is recommended. On 256 mm class beds, such as the Bambu Lab X1 or P1 series, rotate the model approximately 15 degrees. The required footprint is around 240 × 240 mm.

Filament: TPU 95A only
Material required: Approximately 229 g
Layer height: 0.20 to 0.25 mm
Nozzle: 0.4 mm
Infill: 100 percent
Perimeters: 3 to 4
Supports: No
Raft: No
Brim: Normally not required
Print orientation: Print flat exactly as exported

The model must be printed solid. The strength calculations and edge behavior assume 100 percent infill.

Recommended TPU settings

• Print speed: 25 to 35 mm/s

• Use minimal retraction

• Use low part cooling

• Print with dry filament

• Use a slow first layer for reliable adhesion

The model has a large flat first layer, so a brim should not normally be necessary.

Smaller printers

For smaller print beds, scale the model uniformly to approximately 88 percent.

This produces an edge length of around 230 mm while keeping the finger holes large enough for normal use.

Do not scale only one axis, as this will distort the grip geometry and alter the working edge profiles.
