- 30 to 44.5 mm

- 14.5 mm, 5.8 turns at 2.5 mm
The dimensions are fine, you can download the support.
Printing and fitting
- Print in PETG or PLA with 0.2 mm layers and at least 3 perimeters so the thread holds firmly.
- The parts are oriented for printing and need no supports: the base stands on its foot, the screw on its wheel and the head on its support surface.
- Print the test thread first. If it is tight, add 0.05 to 0.1 mm clearance; if it wobbles, reduce it.
- Pass the tie down one slot, around a bar or grille under the foot and up the other slot, then pull it tight.
- Set the height by turning the screw; one turn raises the head by 2.5 mm.
- Only support the card so it does not sag. Do not push it up, the slot on the motherboard could be damaged.

Card
A stronger thread and a flat pad under the end of the cooler to stop the card sagging.
Height
From the bottom of the foot to the support surface, screw fully in.
How far the holder unscrews, so it can be loosened and tightened firmly against the card.
Thread
Outer diameter of the screw.
How far the screw rises per turn.
Gap between the screw and the sleeve. Usually 0.3 to 0.4 mm.
Foot
Mounting
Four slots near the ends. The tie goes down one slot, around a bar or grille under the foot and up the other slot.
Support head
Head
A flat pad under the card. It sits on a pin and keeps its position while you turn the screw.
Cooling
Foot: 10 holes. Pad: 4 air channels.

Printer filament
In the 3MF for Bambu Studio and OrcaSlicer, the parts are already assigned to these filaments (AMS slots), no repainting needed.
All parts on one build plate, oriented for printing.
STL format
A short screw and a ring with the same thread and clearance. It prints in a few minutes.

How to print a card support
Choose the card type and measure how high the end of the card sits above the case floor or PSU shroud.
Set the holder height in centimetres and the room to raise it with the sliders, so it can be loosened and tightened against the card.
Pick the foot mounting, a cable tie or screws, and the head: a flat pad or a groove for the card's edge.
Print the test thread first and adjust the clearance, then download the 3MF or STL with all parts.
Fix the foot with a cable tie, screw the screw into the sleeve and unscrew it until the head just touches the card.
About this tool
This support holds the end of a graphics or network card so it does not sag or pull on the motherboard slot. You set the height with a screw: unscrew it and the head rises, screw it in and it drops.
Pick the holder height in centimetres and the room to raise it with sliders, and the tool works out the sleeve length and keeps at least two threads engaged. The foot has slots for a cable tie, holes for screws, or stays flat.
The head can be a flat pad for the cooler or a groove for the board's edge. Download the parts as 3MF or STL, oriented to print without supports. Everything is calculated in your browser.

Frequently asked questions
Answers to the questions people ask most about this tool.
How tall a support do I need?
Measure from where the foot will stand to the bottom edge of the card. Round that value down to half a centimetre, set it as the holder height and add some room to raise it, then turn the screw up to the card.
How much room to raise it can I set?
Even at the top the screw must stay in the sleeve by at least two threads, and the screw wheel and head sit above the sleeve. So the room to raise it is roughly 1 cm less than the holder height: about 1 cm for a 2 cm holder, about 2 cm for a 3 cm one. If it does not fit, the tool reduces the pitch, wheel and head for you.
What thread clearance should I use?
0.3 to 0.4 mm works on most printers. Print the test thread: if the screw is tight, increase the clearance; if it wobbles, reduce it by 0.05 to 0.1 mm.
Which material should I print the support in?
PETG flexes more and copes with the heat inside a case; PLA is fine if the card does not blow hot air straight at the support. Print with 0.2 mm layers and at least three perimeters for a strong thread.
Do you store my settings on your server?
No. The model and the STL and 3MF files are made only in your browser. Settings are saved in your browser, and a shared link carries them after the #, which browsers never send to a server.
