Phone stand with charging slot, customizable: any angle and phone thickness

A one-piece stand that holds a phone at 65 degrees while it charges. The phone's bottom edge rests on two side pads with front lips, 11 mm apart from the backrest for a 10 mm phone and case. Between the pads, a 45 mm wide opening leaves 40 mm of free run for a straight USB-C plug. The cable runs out the back through a 14 x 9 mm slot. Set the phone thickness (6 to 14 mm), the lean angle (50 to 80 degrees) and the plug room.

It prints flat on its base with no supports; the cable slot is a short bridged tunnel. At 85 x 87.2 x 123.1 mm the stand is solid, so print it with low infill. Measure your phone in its case and your plug's moulding before printing. The phone must be wider than the 45 mm opening to sit on both pads. There are no anti-slip pads.

Parameters

Every slider in the viewer above, with the range the model accepts. The model rebuilds valid at both ends of each range.

Parameter	Range	Default	What it changes
Phone thickness with case	6 to 14 mm	10 mm	Thickness of your phone with its case. The slot is this value plus the play.
Extra play in phone slot	0.5 to 3 mm	1 mm	Extra room added to the slot so the phone drops in easily. Raise it for a grippy case, lower it if the phone rattles.
Lean angle from desk	50 to 80 deg	65 deg	How far the phone leans back, measured from the desk. Lower values lean it further back.
Stand width	70 to 130 mm	85 mm	Overall width of the stand, which also sets how far apart the two side pads are.
Side seat pad width	14 to 40 mm	20 mm	Width of each side pad the phone rests on. Wider pads support the phone better but narrow the plug opening, which stays at least 30 mm.
Plug room under phone	22 to 50 mm	32 mm	How far the phone sits above the base along its own axis, the room for the plug and its moulding. Raise it for a long plug.
Front lip height	8 to 30 mm	14 mm	Height of the front lips on the pads. Taller lips hold the phone more securely but cover more of the screen.
Front lip thickness	2.4 to 8 mm	4 mm	Thickness of the front lips.
Backrest thickness	5 to 14 mm	8 mm	Thickness of the backrest. Thicker is stiffer and heavier.
Backrest length above seat	60 to 140 mm	95 mm	Length of the backrest above the seat. Raise it for tall phones.
Base thickness	6 to 12 mm	8 mm	Thickness of the base plate, which also holds the cable groove.
Cable slot width	10 to 28 mm	14 mm	Width of the cable groove and the slot out the back. Widen it for a thick cable or an off-centre port.
Cable slot height	6 to 16 mm	9 mm	Height of the cable slot through the foot of the backrest.
Phone length (tip-over check)	110 to 200 mm	165 mm	Length of your phone. It only sets how far the base reaches back so the stand does not tip.

Proof: measured on the model

What the design must satisfy and what our CAD engine measured on the model at the default values. Only measured values are shown here; nothing on this page has been printed by us yet.

Requirement	Wanted	Measured
Width of the phone slot between the lip and the backrest	11 mm (10 mm phone and case, 1 mm play)	11 mm
Lean angle of the backrest from the desk	65 deg (the angle slider)	65 deg
Free run for the plug, from the phone's bottom edge down along the phone	32 mm or more (the plug room slider)	40.082 mm
Width of the opening under the phone, between the side pads	45 mm	45 mm
Width of the cable groove out the back	14 mm	14 mm
Height of the cable tunnel through the foot of the backrest	9 mm	9 mm

valid solid, one body, 85 x 87.2 x 123.1 mm, fits a 256 x 256 x 256 mm printer; overhangs: 0.3% of surface would need support.

Print notes

Orientation: As modelled, flat on its base with the backrest leaning up.
Supports: None
Material: PLA or PETG
Layer height: 0.2 mm
Settings: 10 to 15% infill: the stand is solid, about 160 cm3
Hardware: None
Time and filament: About 3 h 30 min and 75 g at the default size: a rough estimate from the model's volume and surface (PLA, 15% infill, about 1 mm of walls, 0.2 mm layers), not a slicer.

Measure your phone in its case and set the thickness slider. If the case is a tight fit, raise the slot play. A test print of the bottom 40 mm checks the slot with your case.
Measure your plug's moulding. If it is longer than about 30 mm or wider than about 25 mm, raise the plug room or narrow the pads.
Plug the cable into the phone first, lead it down the groove and out the back slot, then set the phone on the pads.
A phone with an off-centre USB-C port may need a wider cable slot. There are no anti-slip pads; add small rubber feet if it slides. Stability was not tested with a real phone.

How it was designed

Designed with buildcad's AI agent, checked by the buildcad team. This is the request it started from and an edited account of what it did (more on how text to CAD works).

The request
A desk phone stand for phones up to 10 mm thick with a case, holding the phone at about 65 degrees, charging while it stands: leave room under the phone for a straight USB-C plug and a slot to route the cable out the back.

1
It set the defaults from the prompt
The agent took a 10 mm phone and case with 1 mm of play, an 85 mm wide stand and a phone up to about 165 mm long for the tip-over check, each as a slider. It wrote six checks: the 65 degree angle, an 11 mm slot, 32 mm of open space under the phone, a clear cable path out the back, the width and a flat base.
2
A stand with an open middle
To leave room for a straight plug, the phone rests on two side pads with front lips, and the middle stays open. The first build was one valid body of 85 x 87.2 x 123.1 mm, with only 0.3% of its surface counted as overhang.
3
Probes that missed
Its first rays across the slot returned nothing: once the start point was off, then the direction had its axes swapped. With the direction fixed, the ray found a 4 mm lip, an 11 mm gap and the backrest behind it. The two largest faces of the backrest measured 65.0 degrees.
4
Plug and cable path
A ray from the middle of the phone's bottom edge, straight down along the phone, ran 40 mm before it met the groove floor, against the 32 mm asked for. A ray along the cable route found no material from the groove to the back edge. The slider sweep then rebuilt all 28 extremes as valid single bodies.
5
What it left to the maker
Its reply says it was not test-printed, asks the maker to measure the plug's moulding, notes that an off-centre port may need a wider slot, and suggests low infill and rubber feet.

One run of the agent: 4 min 16 s, about $0.57 of model time at list price (claude-sonnet-5-5). The model code behind this page is the code it wrote, unchanged.
