I made this to be a camera holder for my power rack. Sometimes I want to be able to look at my phone for form reference, workout tracking, photos, watch a video during workouts.. whatever. So this pops in and works pretty well. It is meant so that it will work on either the short side or the long side of the rack

You may need to tweak the scale as I'm not sure how universal rack's sizings are, but mine is for a Rugged brand Half Rack. Print however you want, but I've found standing it up for printing helps the layer lines be in a more structurally stronger direction. Printing it "flat" the lever arm sometimes can snap off easier I imagine.

I super glue 2 1/4-20 nuts into it, then glue some 1/4-20 threaded rod to attach my MagSafe camera mount, but you can use whatever phone holder you prefer. If you have a hex head 1/4-20 bolt it should also fit and glue in pretty nicely.

This is the MagSafe mount I use, https://www.amazon.com/FPN-Magnetic-Tripod-Adapter-MagSafe/dp/B0DK75235Y/ref=sr_1_16?crid=2P6YANNOKUT09&dib=eyJ2IjoiMSJ9.Kk8YegvIljaE3RdfaAOWZyQSb0oKNqZuiBTXU_98JbwvvaSkM44ZzYSt43UTU1FL-JBqgRPEFeU_9OmCFbcJV3XXVm6I4qn8Ct67XRt5aGvlJo-_aKY2aNycr-n7l2nfwbkPCD1SuTqppIpXmxUe_HXvaJ-BkDz2zHejZy8SlpaQ2Sx4lK_VJ1W6gbHW_LBc7HEcka2mQQVU3ozOdj-Jsd6J0FFajMF63yIc46_u_VY.v16RvTbjYWcF8tPvch5YxrYH8l09uy-kGudQDxYFSQg&dib_tag=se&keywords=magsafe+camera+mount&qid=1778286310&sprefix=magsafe+camera+%2Caps%2C170&sr=8-16
But one of the articulated ones would give you more versatility and maneuverability

Print settings however you prefer. I've found outer wall count is more important for strength and durability than infill. I think I did 8 walls/tops/bottoms and 20% infill.

Enjoy.
