My Costa cup lid broke, the slider part snapped and tbf I never liked the lid or the slider part.

The lid was hard to clean and the slider would close itself when you tried to take a sip.

All that is really needed was a good lid.

Using the original seal I designed a new lid.

The OpenSCAD file is included so you can customise it to your liking, a STL is provided of a basic lid and some text.

There is no reason why this can't be customised to fit any cup, you'll just have to get an o-ring seal to fit or print one out of tpu or something.

The original costa cup is a 12oz/350ml that I bought a couple of years ago, I have no idea if they still sell them, but I wasn't about to throw out a perfectly good cup.

I printed in PETG, I do not recommend PLA for hot drinks as it might deform.

I printed mine without the cone shaped internal cutout, because I forgot and added that while printing. You don't need the cone shape, but it'll be stronger and easier to clean. If you don't want it, just set:

c_internal_cutout_dia_bottom = 60.0;

c_internal_cutout_dia_top = 50.0;

to 60.0;
