Injection molding machines are usually quite expensive and bulky. If you don’t have the space or the cash to spend, then using the process of injection molding to create things is practically impossible. However, one maker decided to try and make his own little machine to use in his shop – and he did it for under $100. He also only used tools available to him that can be bought for under $700 total. If you see the video and want to embark on the project yourself, you can find the instructable for the build here.
