Neewer 4M Light Stand Dual "GoPro" Mount

I needed to get some cameras up in the air to record sports, so I bought some Neewer 4M Light Stands.  I then designed the bracket in this make to be able to attach two “GoPro” mount style devices.  For the cameras I use Akaso Brave 7's, however any “action camera” with a GoPro style mount should work.  Some of the finished photos include 2 of these cameras on these mounts.  You may also be interested in my Cheap Sports Multicam GitHub project with software to take 4 cameras recorded files and turn them into a single 4K 2x2 tiled video.

The Bracket

TripodBracket.stl and TripodBracketLine.stl are a multi-colored print and should be imported together (or use TripodBracketMulticolor.3mf).  I printed the bracket in black PETG and used Prusament Prusa Orange PETG for the line which makes it stand out nicely.  The line can be omitted for a single color print.  Print parameters:

• Flat side down, no supports

• Variable Layer Height adds minimal printing time and makes the curves nicer

• 25% infill

• 5 Perimeters

• Gyroid or Cubic infill

• Recommend to print "hot" for better layer adhesion.

TripodBracketPeg.stl is the retaining peg.  One of the great things about the Neewer tripod is the arrangement of the top which allows this peg to go all the way through producing a very sturdy mount.  I printed in black PETG.  Print parameters:

• Print on end;  Yes, really, on the round end

• Add a brim of at least 4mm to stabilize

• 25% infill

• 5 Perimeters

• Gyroid or Cubic infill

• Add a modifier box that covers the notch in the middle of the peg

  • 6 perimeters

  • 50% infill

• Recommend to print "hot" for better layer adhesion

IMPORTANT NOTE: I've had two pegs break in the wind, not in a way that was catastrophic.  Layer adhesion is key with the print direction, and the best fix I've found is to print "hot".  I normally print PETG at 230, but for the pegs I go to 245 and that seems to help a lot.  There's a bit more banding to them, but the visual doesn't matter.

GoProMountingCircle.stl is a “GoPro” style mount.  The base is marked off in 5 degree increments that can be lined up with the line in the bracket to get precise angles between the two cameras.  Print parameters:

• 2 are required per bracket

• Flat side down, no supports.

• 20% infill

• 3 Perimeters

• Cubic infil

• I also like to do a variable layer height and crank down the last 1mm of layers to 0.10 to get a nicer curve, but it's not required.

Each mounting circle gets one M4*5*5 heat set inserts installed in the bottom hole of the mounting circle.  A M5*5*7 heat set insert should be installed in the bulging end of the mount for the screw that secures the mounted device.  Use a M4x8mm button head or cap screw up through the bottom of the Tripod Bracket to attach.

I found that the plastic on plastic had very little friction.  I purchased 220 grit stick on sandpaper and cut a circle to match the bottom of the mount.  See photograph in the pictures section.  Now with the screw tight they will not spin at all.

Optional Hat

For outdoor use a “hat” is available.  On a sunny day it can protect the cameras from direct sun and help prevent them from shutting down due to over-temperature.  On a rainy day it can keep some of the rain off the cameras and help reduce rain drops on the lens.

HatRiser.stl is the support bracket to hold the hat.

• 2 are required per bracket.

• Flat side down, no supports.

• Standard 15% infix and 2 perimeters should be fine.

• 4 M3x8mm button head/flat head cap screw/socket head screw to attach the riser to the Hat.

• 4 M3x8mm flat head cap screw to attach the riser to the bracket.  FHCS are needed to clear the knob on the tripod.

IMPORTANT NOTE: These are intentionally flimsy.  If you drop the tripod with the unit on top (or the wind knocks it over) these are designed to break.  In all but one case so far this has allowed me to reuse the hat itself and the mounting bracket, just replacing these quick to print risers.  I highly recommend having extras available on site.

HatHalf.stl is one half of the Hat.  It is printed as two half pieces because my printer (MK3S) can't print a single part that large.  It would be trivial to combine the two half pieces into a single piece in Fusion if you had a print volume large enough.

• 2 are required per bracket

• Print on end (e.g. middle of the finished hat straight down on the bed), and I highly recommend orienting so the part is in line with the direction of movement of the bed if you use a bed slinger.  Use a brim, but no supports.

• I reduce the infill to 10%.

• Install 4 M3*4*4.2 heat set inserts into each hat half.

Change Log

• 2025-09-16 Uploaded new TripodBracket.stl, TripodBracketLine.stl TripodBracketMulticolor.3mf and TripodBracket.3fd files that remove the need for heat set inserts to mount the brackets that hold the hat to the main TripodBracket and add a small additional tab on the front side that helps prevent the bracket from wobbling on a tripod.

• 2025-11-27 Stopped using Brave 7 LE cameras due to an issue with them, swapped for Brave 7 cameras.  Updated text.

• 2025-12-06 Used for the entire fall season and worked well.  Modified notes about perimeters and print temperatures based on experience.  Added picture and note about sandpaper on GoPro mounts to keep them from spinning.
