Modular Phone Stand Kit | Fits Any Phone | Low, Tall & Desk Clamp | Screw-Together

Your phone, held exactly where you want it: low on the desk for video calls, up high for recipes and tutorials, or clamped to a shelf filming your hobby, from 3D prints to crafts and cooking. 17 parts on one plate. No supports, no screws, no glue, no tools.

Why you'll like it: fits any phone 58-95 mm wide, case on; no floor under the phone, so the charger plugs in at any width; tilts in 15° clicks; and it grows with you: stack columns for height, add the overhead arm for top-down filming, the coin base for weight, or the tripod adapter. Every joint uses the same 24 mm thread, so any piece screws into any other.

What's in the kit (17 printed parts, one plate):

• Round base, 160 mm across, with a threaded socket in the middle

• Two 100 mm columns (stack as many as you like, see the extra column)

• Tilting head with a toothed (rosette) joint and a lock ring

• Universal cradle: a small screw vise that holds phones 58-95 mm wide and up to 13 mm thick, cased or not; no floor between the jaws, so a charging plug fits at any width

• Desk clamp for desks and boards up to about 40 mm thick, plus its screw, two nuts and a pad

• Three printed hex nuts and the knob bolt / knob screws that tighten the tilt, the jaw and the clamp

Three ways to stand it:

• Low: base + head + cradle

• Tall: base + columns + head + cradle

• Desk clamp: clamp on a desk or shelf edge + column + head + cradle

Add-ons (separate files):

• Overhead arm: phone flat above your work, camera straight down

• Coin-ballast base: the same base with eight coin cups, for weight under tall or overhead builds

• Tripod adapter: screws the stand onto a camera tripod (needs one store-bought camera nut)

• Extra column: 10 cm more height per column

Size: base 160 x 160 x 24 mm; column 100 mm usable (112 mm with its screw stub); cradle 134.5 x 41 x 41 mm; desk clamp 67 x 79 x 44 mm.

You need nothing else: no screws, no glue, no tools.

Print settings (what we used):

• Anycubic Kobra X, PETG (black), 0.4 mm nozzle, 0.2 mm layers

• 4 wall loops, top 5 / bottom 4 layers, 15% gyroid, seam aligned (it keeps the thread seam on one side, which helped the fit)

• No supports, no brim, no pauses

• All parts are laid out as modelled; the .3mf is one plate, about 15 h and 322 g of filament

• Other printers and PLA: the STLs should print as they are on any printer and in PLA, but we have only printed them in PETG on the Kobra X; PLA and other printers are untested.

Assembly tips:

• Fresh threads carry stringy leftovers: screw every bolt and screw in and out a few times before you judge the fit or assemble.

• A screw joint always stops at the same angle. Screw the head in until it faces the right way, then lock it with the lock ring.

• Tilt nut clearance was tuned on a real print: 0.5 mm in PETG (0.3 was too tight). If your printer runs tight, scale the nuts up a hair.

• Step-by-step pictures for every setup are in the quick guide (PDF).

What is tested and what is not:

• Printed and screwed together on a Kobra X in PETG (thread test, nut test and a full kit print, all fine). The universal cradle holds a phone (Samsung S21) on the base + two columns, in the Low setup tilted back, and on the desk clamp gripping a shelf edge while filming a print (real photos).

• Not tested: how many stacked columns stay steady on the base, and the clamp on very thick boards.

Add-on files in this download (print only what you need; they all use the kit's thread):

• Overhead arm (3 parts: arm, coupler, second lock ring): needs the kit's two columns, head and cradle. Overhead is the tippiest setup: the phone hangs about 100 mm past the foot, so use the coin-ballast base with coins in its cups, or the desk clamp instead of the base. Over a bedslinger printer, come in from the front below the gantry's top bar (the arm reaches 120 mm); otherwise use the tall setup tilted about 45 degrees down. 2 h 8 min, 43 g. Printed and tested: the arm worked on the first print. Not tested: a heavy phone hanging overhead.

• Coin-ballast base (1 part): a drop-in swap for the kit's plain base: same size and threaded socket, plus eight cups around the edge for coins. 4 h 26 min, 104 g. Not yet printed from this file.

• Tripod adapter (1 part): a round puck with the kit's thread on top and a pocket underneath for one store-bought 1/4"-20 camera nut. Screw the puck onto the tripod, then the head and cradle (or a column first) into the puck. 34 min, 13 g. Printed, but not tested on a tripod yet (we don't own one); if you try it, tell us how it went.

• Extra column (1 part): columns stack, each screws into the top of the one below, and the head screws into the top one. 2 h 6 min, 38 g per column. How many columns stay steady on the base before it wobbles is untested; use the coin-ballast base or the desk clamp for tall builds.

Pictures of the overhead arm, the exploded view, the flat-lay and the tilt are computer renders, not photos. Each add-on has its own Anycubic Slicer Next project (.3mf) with the settings above.

Files:

• kit-all-17-parts-oneplate.stl: the whole kit in one STL, all 17 parts laid out exactly as on our tested plate (needs a 256 x 256 mm bed).

• kit-oneplate-orca-bambu-petg.3mf: the same plate as a project with our settings, for OrcaSlicer, Bambu Studio, Creality Print and Anycubic Slicer Next. It opens with a neutral printer: pick your own printer and keep the print and filament settings.

• kit-oneplate-prusaslicer-petg.3mf: the same plate and settings for PrusaSlicer.

• 00-kit-oneplate-kobra-x-petg.3mf: the exact project we printed on the Kobra X.

• Single STLs, if your bed is smaller. How many to print: base 1, column 2, head 1, lock ring 1, universal cradle 1, universal jaw 1, clamp screw 1, knob bolt 1, tilt nut 3, desk clamp 1, desk screw 1, clamp nut 2, clamp pad 1 (17 parts).

• print-settings.txt: all our settings in plain text, plus this parts list. Tested only on a Kobra X in PETG; PLA and other printers are untested.
