Trinity NSF Wire Shelf - Extension Plug

https://makerworld.com/en/models/227442-3-tier-wire-shelving-rack-clip-bracket?from=search#profileId-247648^ printed 4 of these sleeves and then bought 2 1" x 48" wooden rods and chopped them in half for a 24" shelf extension. probably wouldn't go any higher doing this but the legs seem very stable and rigid. way better than i had expected it to work. to attach the sleeves to the wooden dowel i actually used wood glue and counter sunk a couple of screws through the plastic into the wood… worked just fine. i'm sure there are better ways to do it. this was just easiest for me.would suggest printing the plugs in TPU only otherwise they might break off in there
