Colander 100 mm - pasta strainer, medium 2.5 mm holes, kitchen sieve, no supports

What it is

A round kitchen colander, 100 mm at the top and 40 mm deep, for pasta, salad and vegetables. The flat bottom has 97 holes of 2.5 mm, the 30 degree wall 50 slots of 2.5 mm - so water runs off at the bottom and at the sides. Two grip ledges at the rim. The colander stands on its flat bottom and prints in one piece without supports.

Finer than about 1 mm is not reliable with a 0.4 mm nozzle - for flour, tea or coffee lay a piece of nylon mesh, cheesecloth or a paper filter into the sieve.

Free sample

This model is free - an honest sample of the series, so you can check fit, hole size and print settings on your own printer before you buy. The family has 12 models, it is also available as a discounted set, and the complete set holds all 60 sieves of the series (colanders, stackable sieve inserts, sink and drain strainers, paint strainers, fan dust filters, aquarium intake strainers and XXL sieves).

What goes with it

optional: nylon mesh, cheesecloth or paper filter for anything finer than 1 mm

Which filament - food contact, heat, chemicals

Food contact: no 3D print is food-safe by itself - food residue and germs settle in the layer lines. Use a filament with a food-contact declaration of the maker (EU 10/2011 and/or FDA 21 CFR 177), print with a stainless steel nozzle (brass nozzles can contain lead), wash the part right after use and replace it when the surface gets rough. All at your own risk.

Hot pasta or potato water (close to 100 °C): PP (polypropylene) with food-contact declaration - it stays firm up to about 100 °C. PETG softens from about 70-80 °C: use it cold (salad, berries, rinsing rice) or let the water cool down first. PLA never with hot food (soft from about 55 °C).

Dishwasher: PP yes (top rack), PETG only on a cool programme, PLA no.
