Phone holder helper for telescope daylight polar alignment

Just a little helper object to hold my phone when doing daytime polar alignment. 

Previously, I held it by hand and the camera bump made it difficult to keep flat while adjusting the mount. 

STL is sized for a Pixel 3a XL. Fusion source included in case you want to redo it for a different phone size (it's all parametric). 

Print 1x of holder.stl and 2x of peg.stl. I used PETG .20mm with 20% infill and that seems fine.  The overhang that holds the phone in place is shallow enough that no supports are needed. The pegs are friction fit into the holder - just carefully work them into place. The flat spots on the pegs are intended to put no-slip rubber bumpers (like are on cabinets/drawers) but it works fine without them too. 

Excuse my crappy F360 skills - shout if you have questions/issues resizing things.
