This is a Non-AMS version of the Multiplication table design Mathematicus by CopyKnight. I had to remake the main table to with embossed numbers so that they can be printed without AMS. 

A pause is already added in the print profile where you can switch the filament to another colour of your liking. 

I didnt add the numbers on the bar however, so you may have to write them manually. I intend to make an updated version if i have time, but no guarantees 😅

Note: I tried to contact the original creator to publish this as a remix, but have not got any reply for a week now. Credit for the original design still goes to the main designer.
