LEARNING MULTIPLICATION TABLES KEYCHAIN

Sooner or later, the time comes for the little ones at home to memorize their multiplication tables. It's likely one of the first rote memorization exercises they'll have to undertake, and they probably won't enjoy it... Therefore, to make the most of every moment for practice, these types of items are very useful. We can print the templates and combine them with an attractive keychain. They are the perfect size to carry in a pocket, allowing for a surprise review whenever an opportunity arises

RECOMMENDED MATERIAL:

I recommend printing with PETG. The keychain will endure a lot of stress from being in pockets, handled by children, and so on. PETG is more flexible and resistant than PLA. Nevertheless, a profile is available for each material. I have also uploaded an .obj file with all the tables grouped together to fit on a 256x256 build plate. At the end of this publication, you will find a video on how to color an .obj file in Bambu Studio

NOTE ON THE TWO LEARNING VERSIONS:

Two Learning Formats Included / Incluye Dos Formatos de Aprendizaje

This collection now includes two versions of the multiplication tables, both mathematically correct and commonly used in different educational systems.

Spanish Version

• 2×1 = 2
• 2×2 = 4
• 2×3 = 6
• ...

This is the traditional format used in Spain and several other countries.

International Version

• 1×2 = 2
• 2×2 = 4
• 3×2 = 6
• ...

This format is commonly found in educational materials from Germany, English-speaking countries, and other international resources.

Both versions produce exactly the same results. The difference is only the order in which the multiplication table is presented

MODIFICATIONS TO THE ORIGINAL MODEL:

I printed the original model, but my daughter didn't like it, saying the numbers weren't very clear and were too small. So, I extracted the number sections from the original STLs, enlarged them, and then designed a new base. This new base is similar to the old one but slightly larger, providing a small extra margin around the frame. I also corrected a minor error in the first multiplication of the five times table. Afterwards, I combined the base frames with all the numberings and loaded them into Bambu Studio. This way, all the tables are organized on a 256x256 print plate in two single files, making color changes much easier

MULTICOLOR PRINTING USING “PAUSE AT LAYER”:

You should choose the correct profile, as I have uploaded some that require an AMS, and others that can be printed without this device by utilizing the pause-at-layer feature to change the filament. If you are not familiar with this method, I will include two explanatory videos at the end of this publication
