3D Printed Light Gun Holster Mount Review: Fit and Stability
Quick Summary
A light gun holster mount has to hold the gun steady and at a usable height without shifting, rattling or dropping. Judge it on fit, meaning the cradle matches the gun's body, and on stability, meaning the gun stays put when you press on it from the side and front. Measure your gun before you buy or print anything.
Measure the gun's width and grip depth and compare them with the listed dimensions.
A gap of a few millimetres can be shimmed with a snug strap or pad; a centimetre gap will tilt the gun.
Press on the gun from the side and front to check for flex or pivoting.
An AimTrak will likely wobble in a Sinden-specific cradle because its shape and grip angle differ.
Test a printed cradle with the actual gun before fixing the mount to a surface.

What a Light Gun Holster Mount Has to Do
A light gun holster mount has one job: hold a light gun steady and at a usable height without the gun shifting, rattling or dropping when you move the cabinet or the player bumps the stand. Fit and stability are the two properties that decide whether a mount is worth printing or buying. A mount that looks good but wobbles under a firm grip fails the basic test.
When you judge a mount, check four things. The cradle should match the gun's body shape closely enough that the gun sits without forcing. The mount should hold the gun in place during reloads and quick draws. It should attach to a surface you actually have, whether a cabinet side, a panel or a shelf. And it should be printable with ordinary materials and settings, since many of these designs are shared as free files.
Fit is the first test. Measure your gun's width and grip depth before you choose a model, and compare those numbers to the listed dimensions. A gap of a few millimetres is usually tolerable with a snug strap or pad; a gap of a centimetre means the gun will tilt. Stability is the second test. Press on the gun from the side and from the front. If the mount flexes or the gun pivots, the design or the print needs work.
Sinden Light Gun Holster Options Compared
Sinden owners have several holster options, from the optional accessory to free replacement files. The main choices differ in how they hold the gun.
For a Sinden gun paired with a bullpup-style look, a dedicated bullpup mod changes the feel without any screws or glue. You can explore the Sinden Bullpup Mod to see how it attaches in seconds. It is a different category from a mount, since it changes the gun's shape rather than holding it on a surface, so choose based on whether you want storage or a feel upgrade.
AimTrak Light Gun Holster Options Compared
AimTrak holsters are fewer in number, so the choice usually comes down to a single listing.
Because AimTrak guns differ from Sinden guns in shape and grip, a holster made for one will not fit the other. The AimTrak's body is wider at the base and has a different grip angle, so a Sinden-specific cradle will likely let it wobble. Before you buy, measure your AimTrak's width at the widest point and the depth from trigger guard to backstrap, then compare those numbers to any listed dimensions. A gap of a few millimetres can be shimmed with felt pads; a gap of a centimetre means the gun will tilt.
Ask the seller two questions: does the holster include screws or adhesive tape for mounting, and is the cradle sized for the original AimTrak or a modded shell? A loose-fitting holster that merely rests the gun is fine for storage but will not survive play. If you plan to mount it on a cabinet side, confirm the screw holes align with your panel thickness, thin MDF can crack if the screws are over-tightened. For a quick retention test before committing, set the gun in the holster and tip it 30 degrees; if it slides out, the fit is too loose for active use.
Printing a Light Gun Stand: Settings and Materials
If you print your own stand, material and settings affect how well the mount holds up under use.
For most light gun mounts, a 0.2 mm layer height with three perimeters and 20-30 percent gyroid infill is a reliable starting point. If you want a cradle built for the pulse mod, see the Sinden Pulse Mounts. Print the cradle with the opening facing up so the layer lines run across the grip rather than along it, this reduces the chance of splitting when the gun is pushed in. If the model has overhangs on the mounting flange, use tree supports and remove them carefully with flush cutters. The Sinden holder listing recommends printing vertically, which may cut support material and improve surface finish on the visible faces. Follow the listing's orientation guidance for each model, since a wrong orientation can leave the cradle weaker along the layer lines.
After printing, test the fit with the gun before fixing the mount to a surface. Avoid over-tightening screws into printed parts, and use washers to spread the load.
Pro Tip Print a small test piece of the cradle first to check fit before committing to the full mount.
Checking Light Gun Holster Mount Compatibility
Before you buy or print, run a short compatibility check:
Measure the gun's width, height and grip depth
Compare those figures with the model's listed dimensions
Confirm which gun family the model is designed for
Check whether the mount is designed for left, right or either side
Confirm the mounting method matches your cabinet or panel
Ask the seller whether fixings are included
Compatibility is a common reason mounts get reprinted. A listing that names a gun family is a good starting point, but the only reliable test is a dry fit with the actual gun. If the gun does not seat without force, do not pry it in, since that can crack a printed part or damage the gun's housing.
Keep the gun's electronics and cables in mind as well. Make sure the mount does not press on any buttons, trigger assemblies or cable exits. For ideas on fitment around controllers and cabinet parts, see this guide to custom arcade controller aesthetic mods.
Mounting Hardware and Surface Considerations
How you attach a mount often matters as much as the mount itself. Common approaches include screws into a wooden cabinet side, double-sided tape on a smooth panel, and brackets or spacers that clear a curved or uneven surface. Each has trade-offs.
Screws give the most secure hold and suit a solid wooden cabinet, but they require drilling and leave holes. Adhesive tape is quicker and reversible on some surfaces, but it can fail on textured or painted panels and under the weight of a gun pulled hard. Spacers help when the mount needs to sit a few millimetres off the surface to clear cables or a cabinet lip.
Test the surface before you commit. Clean it, press the mount on, and load it with the gun. Leave it overnight and check again. If the mount creeps or the tape lifts, switch to screws or a bracket. For folded metal or thin panels, check that the fixings will not bend the surface under load.
Choosing a Mount for Your Arcade Setup
The right mount depends on how you use the gun. If you want storage that keeps the gun off the floor and out of the way between sessions, a free or low-cost printable holder is a sensible start. If you play often and need the gun held firmly through heavy use, prioritise a design with a tight cradle, a mounting method that suits your surface, and a print in a tougher material such as PETG.
For a setup that needs to look finished, consider how the mount sits alongside the cabinet artwork. A broader retro shooter light gun modding guide can help you plan the full setup around your mount. A mount that matches the gun's profile and sits flush against the cabinet side reads as a deliberate part of the build.
Start with the fit test, choose a mounting method your surface can hold, and print or buy only after you have confirmed the dimensions. A mount that fits and holds is worth far more than one that simply looks right on a product photo.
Frequently Asked Questions
What should you look for in a 3D-printed light gun holster mount?
Check that the holster cradles the gun body without pinching the trigger guard or blocking the sensor bar, and that the mount holds the gun steady when you pull it out. Look for a design that lets you remove the gun with one hand. Confirm the mounting method suits your cabinet or panel material, since double-sided tape, screws and brackets each behave differently over time. Test fit with the actual gun before committing to a long print.
Are 3D-printed light gun holsters compatible with Sinden light guns?
Many printable models are designed for Sinden light guns. Compatibility still depends on the exact gun version and how the model is sized, so compare the listed dimensions with your own gun before printing. Where a listing gives print orientation or a left- or right-side option, follow it, because a mirrored print is needed to fit the opposite side of a setup.
Can you use a 3D-printed holster mount with an AimTrak light gun?
Read any holster listing carefully and check whether the mount needs a bracket or spacer for your surface. Measure your gun body and mounting space first, then decide whether a purpose-built model or a remixed design will fit better.
How do you mount a light gun holster in an arcade setup?
Start by choosing a surface that is flat, clean and strong enough to carry the gun's weight during repeated use. Common approaches are adhesive or double-sided tape for lightweight holders, screws or brackets for cabinet panels, and spacers where the holster needs to sit clear of the panel. Dry-fit the holster with the gun before fixing it permanently, and make sure the gun can be lifted out without catching on wiring or nearby controls.
