The reasoning of my shape is because I like the results I have gotten in WPBD using a top and bottom truss. Although I do wish the top was more arch like but I found it difficult to make but given more time and experimentation I believe it will become more arch like in the future. It was shaped to be fairly condensed using short pieces as they were more stable in testing also it is not too expensive as the longer pieces are and it does not require too many gussets as if done using shorter length peices.

 I felt it was unneeded to put the lenghts and dimensions as it is color coded and each color has a fixed length. White: 1.25", Yellow: 3.375", Red: 5"

The gussets are blue dots and are all made of two 180 degree grooved gusset plates put together so the cross bars can be added to attatch the two sides. the only exception is there are 5 gussets per side that are 180 degree grooved gusset plate and 360 degree grooved gusset plate together, these are used in the middle where the gusset has bar located to the top, bottom, and both side.



Height: 6.77"
Lenght: 25.25"

There were not many changes as I wanted to keep it as simple as possible but some of my changes are as followed. The base was made of five red bars, I changed to six yellow as I feel the shorter ones will be more stable and offer more connections on the upper level. Second the highest level was just like the middle but I changed it to be like the bottom in hope that it would be more stable and also to cut cost. Also the bars that connect the two sides was red but I changed it to yellow bars as it would condense it and also cut cost a bit. These were the major changes.

I learned that some time material is predetermined in length and thus options are limited and some designs require tweaking or may not be possible.
