anyone make their own pvc pipe rack for fodder growing?

got plenty of 1/2 and 3/4 and 1 inch etcPVD... lots already cut up plus and T ,s and couplings and Elles.......from previous not glued up projects......
so what dimensions any pics yall???? dont wana use wood..even though got plenty wanna set it on counter... warm upstairs.. was growing in basement but colder there now. so its slow growing my first batches..
I grew it in 6 "beds" covered with framed removable hardwarw cloth "lids" last year. but got it started late so they never got it a lot.
Some of the hardy winter wheat is still alive.. I guess I should have suroounded the frames with pine needles...
Dont wanna spend the pricey bucks for ready made... since I have so much stuff now.....
thanks yall
