"Heck Meck" soap dispenser

thingiverse

I designed this fan gizmo for my elderly parents as a surprise because they love playing "Heck Meck". But friends asked for copies too, so I emailed Reiner Knizia, the game inventor, to see if I could share the design since the worm design is part of the game with copyright (see https://www.knizia.de/ for details). He was kind and allowed me to publish it for non-commercial use - he even requested a soap dispenser. I made three sizes: XVII80, XVIII90, and XVII100, which hold 2dl, 2.75dl, and 3.5dl respectively (don't ask about the naming). The thread is the same size in all cases: diameter 27mm with 4mm of elevation per revolution. This works well with common soap brands like "Bliw" and "Palmolive". For a stronger thread, I recommend using the support element (set it to 60% fill if you're using slic3r) - don't forget post-processing too.
