Tupperware Crisp-it Centre

Inevitable you eventually lose the centre of your "Tupperware Ware Crisp It" ( I probably accidentally chucked ours in the garbage) and your lettuce or greens forever goes soggy . . . . . . waaaay quicker than before so here is a plan for replacement.

If you have SCAD, the SCAD file lets you easily change sizes and hole placements -

Small holes are automatically half the radius size of the larger ones.
[UPDATE to the SCAD file, 23 Jul 2022]
If the height of the central spike is set to zero the spike is removed and replaced with an extra drain hole. This makes it more useful for non-lettuce items like spinach.
The STL file for the spikeless plan is the TWlettnspike.stl file.
This can also be printed upside down without any support.,
