This centered shape design tree clock is designed by Laser Cut Delights. 

We laser cut this design from 3mm mdf and is 30cm...NO MECHANISMS are included with this item, but you can purchase them from a seperate listing.

The hole is 8mm wide/tall to fit our mechanisms but if you need this a different size please let me know. 

PLEASE NOTE: There will be a 3mm mdf circle behind this tree (regardless of mdf thickness you choose for the actual clock) so that you cannot see the mechanism through the design.  Therefore you will need to purchase the long spindle if you order this clock in 6mm mdf (as the total thickness will then be 9mm) and the medium spindle if you order in 3mm (as the total thickness will then be 6mm).
