Does it really matter to always see how many minutes are left there before we are late? Does it really always matter how late are we, once we are already late? Here is the clock that tells you with precision only when there are less than 6 minutes left till the full or half an hour. And if you are more than 2 minutes late - who cares :) 

Minimalistic wall clock designed to fit Maker's Supply Clock Components Kit 011. Clock is quiet big, diameter is 34 cm (13.4 inches), however it can be printed on A1 mini since it is built from parts. The 2 parts slid into place quiet firmly - use a flat object to assist you with insertion into the provided slots, if needed. I updated the model to make insertion easier. In extreme cases use a small hammer and a piece of wood to get the insert into place, but I really hope it won't be necessary. However, tight fit was my priority to prevent any neer for glue or screws.

Assembled joint is on the photo below: 

I printed on A1 mini, textured stock base plate with PLA.

Note that 2nd plate shall be printed twice (parts are identical).

Clock hands are printed in order to be long enough for the clock design. Since tolerances are really tight, I created multiple variations with variable hole sizes in a separate print profile. The original size which works for my Clock Components Kit 011 is in the main profile. In additional profile there is 1 variant with smaller hole and 4 variants with larger holes. If even this isn't sufficient, please, reach me through the comments and I will prepare additional ones. 

I successfully fitted some other generic clock mechanism to my model, including one of the hands variant.

Please, consider boosting my design if you like it. Thanks!
