Hi Epiphyte,
Sorry for the slow reply!
I'd much rather over than under engineer something like this.
These are the two threads that I based my build on (one has some strain and deformation calculations in it, I found them really helpful.
Wrasse retreat
Frank the tank
I used the deflection calculator @
8020 to ensure I had minimal deflection this is especially an issue with the horizontal beam and because my tank is only 3 ft long but very tall I needed a larger 45 x90 to support it as I didn't want middle supports for access reasons.
I didn't want to drill the t-slot myself so I used in slot connectors listed below they were easy and are very strong, somewhere I found a list of different connector strengths
https://fandl8020.com/wp-content/uploads/2015/01/EBN-Spring15.pdf and picked appropriately.
The main thing that you want to avoid is racking so i'd add bracing to the stand design that you have shown above in the form of 90deg corner gussets. This is to prevent the stand from collapsing if lateral forces are applied.
I'll put some photos in the next post.
I used the following materials: ordered from
motedis, however, i'd be tempted to use v-slot from
Ooznest | 3D Printers & CNC Machines | Parts, Kits & More as they are based in the uk and i've had good service from them when building my light.
