Today I built the last remaining part for the injection molding machine; a spring mount for the actual barrel that will contain the melted plastic. With this, you can put your mold a few millimeters under the nozzle and when pressure is applied from above, it gets pushed down against the mold, giving a decent seal. 

But now its time for coffee to get some energy back. Unfortunately I experienced a nasty customer trolling and threatening me despite me being friendly, trying to solve the issue and even issued a refund. But thats the downside of doing business, sometimes you have to deal with some rotten eggs. Telling from some forum threads, its apparently not his first time making trouble. Thankfully the mails I get once a week or so from customers praising me for my great customer support and innovative product is what gets me up in the morning. Thank you, and keep em coming!
