3D printed teamaker filter holder

Problem

There is a teamaker. The filter assembly needs to be removed for refilling the vessel with water, and the filter with tea leaves.

For that, the filter either needs to be placed on the cupboard, where it leaves a stain, or to somewhere else where there is a risk of cross-contamination, or requires to be held which blocks one hand.

Solution, old version

The top of the filter assembly is a mushroom-shaped knob. This suggested the possible shape of the adapter. There is a cupboard conveniently positioned with its bottom side just where a holder adapter could be.

The adapter was made by 3D printing, due to the operation simplicity, and attached to the cupboard with a piece of foam-cored double-sided tape.

The part was parametrically modeled in OpenSCAD. The inner width was dictated by the width of the mushroom top, the gap width by the width of the stem, the inner height by the height of the top. All plus some safety coefficient to not be too tight. The depth was dictated to be 25mm by the width of the double-sided tape. The top was made somewhat wider, to provide more area for the tape to stick and hold.

The printing took about 20 minutes. There was some minor filament seizing that was manually assisted. The part was oriented to make the tensile load parallel to the layers, and to print without need for overhangs.

After printing, the top layer that was to mate the doublesided tape was heated with a torch and pressed against glass, yielding a smooth surface. It was then briefly licked with a dremel mill, to make it a little rough to provide more area for the adhesive. Probably an unnecessary overkill.

Deployment

The part functions as designed. The tea filter drips surprisingly little, grossly limiting countertop staining in comparison with the earlier handling.

New version

After getting a request for more, the design was improved and modified.

The size was shrunk a little, few millimeters were taken from both width and height, the gap was made narrower, the walls were made thinner a notch which also solved the filament jamming within the infill layer.

The entry sides of the gap were chamfered for easier access.
