Flat Offset Motor Mount -0.5mm

Fine-tune the motor position with the 3D SRP Flat Offset -0.5 mm anglewinder mount

When preparing a slot car enters the fine-tuning phase, major changes are no longer the solution: what makes the difference is the millimetric control of each component. The Flat Offset Motor Mount -0.5 mm (ref. SRP00783) from 3D SRP meets this need exactly, allowing the motor position to be shifted by 0.5 mm from the standard configuration of an anglewinder system.

Main features

• Anglewinder system: designed to mount the motor at an angle to the rear axle, combining a good centre of gravity with efficient transmission.
• -0.5 mm offset: precise correction of the motor position to adjust transmission tension or compensate for chassis tolerances.
• FDM carbon manufacturing: 3D printing with carbon material that provides rigidity and lightness, essential in a competition mount.
• Flat finish: flat profile that favours a clean and stable mounting on the chassis.

Assembly and preparation

For optimal performance, it is recommended to glue the single-flange bearings or bushings before installing the mount on the chassis. This step ensures that the rear axle operates without lateral play and that the transmission remains aligned under any racing conditions. The adjustment of the -0.5 mm offset can be the difference between a crown gear that lightly rubs and a transmission that runs smoothly.

Who is this mount for?

It is designed for tuners and drivers who work on their chassis in depth and understand the importance of managing motor offsets. If your standard setup presents excessive tension in the transmission or you need to compensate for the geometry of a custom chassis, this -0.5 mm mount is the right tool. It is also useful when combined with different crown gears or pinions that require repositioning the motor to maintain the correct mesh.

Frequently asked questions

What is the difference between a mount with offset and one without offset?

A mount without offset positions the motor at the reference position of the design. A mount with offset shifts that position by a specified value —in this case -0.5 mm— to adjust the distance between pinion and crown gear, compensate for manufacturing tolerances of the chassis, or achieve the ideal mesh point in the transmission.

Is it compatible with any anglewinder chassis?

Compatibility depends on the mounting dimensions of the specific chassis. Check the specifications of your chassis before placing an order. 3D SRP manufactures different variants of mounts to fit various geometries.

Why is it recommended to glue the bearings before assembly?

Single-flange bearings or bushings may have a fit with some play in the printed mount housing. Gluing them ensures they do not shift under the load of the rear axle, maintaining alignment and preventing vibrations or premature wear.

What advantage does carbon material offer in an FDM printed mount?

The carbon fibre filament used in FDM printing improves the rigidity of the part compared to conventional plastic, reducing flex that could alter the geometry of the transmission under load. Additionally, its lower weight helps not to penalise the car's centre of gravity.

Can I use it in a competition setup?

Yes. The level of precision offered by a -0.5 mm offset and the rigidity of the material make it suitable for club-level competition preparations. Always check that your championship regulations allow the use of 3D printed parts.

The 3D SRP Flat Offset Motor Mount -0.5mm (SRP00783) is a FDM carbon 3D printed anglewinder motor bracket designed for slot car chassis tuning. The -0.5mm offset allows fine adjustment of motor positioning to optimize gear mesh, reduce transmission tension and compensate chassis tolerances. Recommended use with single-flange bearings glued in place for maximum precision. A must-have part for serious slot car builders looking for millimeter-level setup control.
