Water-molecule desk tidy

Sort pens and clips in an H2O molecule

A desk tidy built as a water molecule: one large oxygen cup for pens, with two smaller hydrogen cups bonded at a wide angle for clips and erasers. H2O is moulded on the front. A science-teacher gift that earns its place on the desk.

Questions

What size is the water-molecule desk tidy model?

The water-molecule desk tidy model measures Ø 92 mm, 74 mm tall. That is Base A; 2 more bases are built on. You can change every size in the free SO3D.xyz generator before you download it.

Does it need supports?

No. Print the big oxygen cup red and the two hydrogen cups white, like a school model. Prints as shown on its floor, no supports.

How much filament does it use?

At most about 138 g of PLA (111 cm³ printed solid), roughly $2.76 of filament at $20 per kg. Normal infill uses less.

Can I change it?

Yes. Open it in the SO3D.xyz generator (free, in your browser), change the size, walls, dividers, holes, text or anything else, then download it as STL or 3MF for your slicer.
