HA Series Buffer Hold Open Block

A new item to help out with changing the PTFE tubes on the H2 Series printers. It's a buffer hold open block to help you with the removal of a PTFE tube. I found it hard for me due to the way I have my H2D set up to hold it over and then push the PTFE tube holder in to release the tube. This worked great in my testing of it. In my two prototypes I have it with the words H2 Series but the text are a tad to small so the final version will not say anything. I guess if I really want it, I could print it with a .2 nozzle but I don’t think it’s that important to have it.
