Drain cover, made to measure

Measure the opening of your drain with a calliper or a ruler — across a round one, side to side on a square one — and we draw a cover for it, with a grid of small holes or straight slots. A short collar underneath drops into the opening and keeps the cover centred, and a rim rests on the floor around it. It prints upside down with no supports.

What you need to hand

A calliper or a ruler for the opening of the drain: across a round one, side to side on a square one.
How far the collar can drop into the opening, if you want one.
Your nozzle size and the filament you will print it in.

Your drain

Measure the opening the cover goes into, at its top edge: across a round one, side to side on a square one. Measure in two directions and give the smaller figure.

Shape of the drain opening

Round or square, as the opening in the floor is.

Drain opening (diameter, or side if square)

Measure across the opening the cover goes into, at its top edge: the diameter of a round drain, or the side of a square one. Measure in two directions and give the smaller figure.

The cover

How far the collar reaches in, how far the rim reaches over the floor, and the holes. The bars between the holes and how snug the collar is are under Finer adjustments.

How far the cover reaches into the drain

A short collar under the cover that drops into the opening and keeps the cover centred. Set 0 for a flat cover that only rests on the floor.

Rim over the floor

How far the cover reaches past the opening on every side, resting on the floor.

Thickness of the cover

The flat plate with the holes in it. Thicker is stiffer and takes longer to print.

Holes or slots

A grid of small holes, or straight parallel slots.

Hole size, or slot width

Across the corners of each hole, or across each slot. Smaller keeps more out of the drain; larger lets more through.

The printer it will come off

Set these to the nozzle you will print with and the filament you will use; what is filled in is only our usual setting. The nozzle decides whether the bars and the plate come out the thickness we drew. The filament does not change the model.

Nozzle size

The nozzle you will print with. It does not change the model — it decides whether the bars and the plate come out the thickness we drew.

Filament

Only a note on where each filament suits. It does not change the model.

Finer adjustments

Bar between the holes

The plastic left between neighbouring holes or slots.

Fit clearance of the collar

How much smaller than the opening we draw the collar, across. More drops in more easily and centres less closely.
