Got these 1/2" 250mm aluminum arms off eBay for about $1 each. Not easy to find tube aluminum locally and to ship it from Mcmaster-Carr or other supply type place is pricey. Not being in any hurry, I waited for the slow boat to bring these. 3mm hardware with elastic stop nuts. Tried to get SS at the WRAM show from the Micro-Fastener outfit but he didn't bring any SS metrics in hex head. The plastic stand offs came from a kit found on eBay auction. There's more available.
