designed these support for the intex cover. the bracings are electrical pvc conduit 19 mm (3/4") in order to install this support you will need to print 1 support center and 5 support side wall. the length of the electrical conduit was determined by first installing the conduit en then installing it above the pool, from that point on determined how much should be cut of.

the side wall supports are what tighter than the center support i solved this by using a dremel sanding tool to increase the diameter a bit

Update: unfortunately PVC conduit wasn’t the best choice as the pvc becomes flexible due to the heat generated by the cover. So I need to find an other solution for the bracings.
