Final Supporting Arch
I have had a difficult time naming each of these individual pieces, and this one has changed from ‘upper arm piece’ to now ‘supporting arch’. The original design had two of these pieces, one at either end, but I found that that wasn’t necessary.
The first picture shows just how large the piece is compared to the bed of my 3d printer. The design actually called for a bottom piece that is 2.54 cm wide, but I had to shrink that quite a bit to fit into my printer.
The second picture shows the comparison between the first arch I printed and the new one. I cut off one of the legs of the old arch, as I often find pieces of old prints to reuse rather than printing out an entirely new one to serve a similar function
