VESA Mounted Phone Holder

thingiverse

I use my phone as a webcam for Zoom and needed something to hold it, so I made this VESA mounted adjustable arm with springloaded phone holder for my PC's monitor.. It's a modified 100x100 swivelling VESA mount, with a sturdy arm that reaches to 10cm behind the top of my 23" monitor. From there it uses adjustable modular arm sections, with both short and long sections to choose from, and the option to double up the arms for extra rigidity. From the Arms it goes into a rotation joint, and finally to a springloaded phone clamp. VESA Mount: Modified so the hinges are now separate from the base plates and attached via lugs so they can be printed in a stronger orientation (Monitor and swivelling 'wall' sides). Also you can now use two shorter bolts (M6 x 50) instead of a single long one, utilising the nut carrier added into the centre hinge (monitor side). On the swivelling side there is a thick arm that reaches up to the top of my 23" monitor (approx 110mm above the upper VESA screws) and 100mm behind . You need - 1 x VESA Monitor Plate.stl 1 x VESA Monitor Plate Hinges (Orientated so the corner cut outs point to the plate holes) 1 x VESA Wall Plate.stl 2 x VESA Wall Plate Hinge.stl 1 x VESA Wall Plate Arm Modular Arms: The short arm sections measure 130 x 30 x 10 (100mm from pivot to pivot) The modified long sections measure 270 x 30 x 10 (240mm from pivot to pivot) In the picture you can see I used 2 long sections and one short, enabling me to reach over the monitor for low down / table cam type work, despite the monitor sitting on a 6" tall Amp. (My setup allows for upto 660mm of movement, from 10cm behind the top of my monitor).. I've also doubled the arm sections up to: a) take more weight at extension, and b) Add rigidity, although single sections can be used if you prefer, as per the original design... The arm sections are 'handed', one having a recessed M5 nut hole and protruding 'ratchet' lugs, while the other has a plain face for the Knob and indented 'ratchet' holes.. You will need one of each to utilise the inbuilt nut carrier and knob, and for the 'ratchet' to engage properly. When printing, either single or doubled arm sections, you need to figure out which type you need, 'Knob' or 'Nut'. Start from the end of the VESA arm, which is a 'Nut' end, so you'll need a 'Knob' section to mate to the 'ratchet' and from there work forward thru each joint, deciding which type you need.. If doubling up the arms, the outer sections need a 'Nut' AND a 'Knob' while also having corresponding 'ratchet' sides between the outer sections... (you'll see what I mean when you look at the STL's) All sections use M5 Nuts and 'set screw' bolts, the bolt length depends on how many arm sections you use. Each arm section is 10mm wide, plus another 10mm in the knob, so for my middle joints, using double arms, i've got 4 x sections and a knob, requiring a 50mm bolt.. A single section arm would be 30mm.. You need - your choice - mix short and long sections for your needs :) Arm Short Knob.stl Arm Short Nut.stl Arm Long Knob.stl Arm Long Nut.stl Rotation Joint: The rotation joint at the end of the arms allows full Up/Dn & L/R adjustment of the phone clamp.. (plus a small degree of swivelling from the VESA mount) You need: 1 x Rotation Joint.stl Phone Clamp: The springloaded (or elastic band) phone holder part is a simple clamp with upper and lower 'claws' that start at 12mm wide and taper down to 5mm, enabling a wide variety of phone sizes, while also keeping the phone tight and centred.. The clamp is 58mm wide at rest, and upto over 90mm fully open (depending on springs used) The distance between the outer edges of the clamps spring mounts, when closed, is 44.8mm. Use a 40mm long spring for a small amount of tension from closed, but one than can stretch upto 70mm.. You need: 1 x Phone Clamp.stl I use a Samsung S9 in mine, landscape and rear facing for the better camera and it fits perfectly. It holds it reasuringly tight, but not stupid tight either (of course the springs you use will play a role in that). It's stable on the monitor (with doubled arms) and doesn't de-stabilise the monitor either, despite only being a 23"..
