This is a chocolate bar mold I designed, it should be almost an identical copy to the "Divine chocolate" company's chocolate bar shape and size.

For the chocolate recipe, I just melted Kirkland semi-sweet chocolate chips using the bowl in boiling water method, and then poured it in after spraying some cooking oil on the mold. I then put it in the fridge overnight. I ran some boiling water over a knife till I thought it was hot then I cut the excess chocolate off of the mold. then I ran some hot tap water on the mold and tapped out the chocolate bar.

The chocolate is very hard to take out, so I am developing ways to make it easier and will submit the perfected design when it is ready. If you have a flexible filament, and use it, you will probably solve this issue.

To solve the Issue above you can print out the Negative bar and make a silicon mold with it. To do that follow the below instructions:

• Buy food grade silicone (such as https://www.amazon.com/Silicone-Making-Rubber-Platinum-Liquid/dp/B08CVQJ4YD/ref=cm_cr_arp_d_product_top?ie=UTF8)
• get plastic cardboard (the stuff "vote for me" signs are made of)
• use a glue stick to glue the negative to a base piece of plastic cardboard
• cut the plastic cardboard to make a box around the negative
• use hot glue to seal the edges of the plastic cardboard to the base cardboard
• mix silicone according to the instructions that came with it
• pour enough silicone into the mold to fully cover the negative by at least 1/4 inch
• let it rest till hard (the instructions will probably say)
• take apart box and remove the negative
• you now have a mold
