Trim Wheel for flight simulator. Hall effect sensor is highly accurate. Easy to mount. Easy to tension

Here are the model files for TWP (Trim Wheel Pro). It is an analogue elevator trim which can be used to precisely control the elevator trim of your aircraft in flight simulator.

More information, assembly instructions, and code can be found on my website. 

All parts have been printed in PETG, on a Prusa MK3S at 0.2mm layer height. No supports are required but will require the purchase of additional components and a tiny bit of soldering. 

Note: I printed the base on a textured sheet to give a nice finish, the other parts I printed on a smooth sheet. The 3mf files show the printed parts in the correct print orientation but you can print each part separately if you wish.

Edit 28/01/2024: Made minor changes to tolarences / chamfers etc.

Edit 06/03/2024: 

• New tensioner design to use a single tensioner screw for even and convenient tensioning

• Removed uneeded cap + now unneccesary countersunk screw

• Redesigned wheel now cap has been removed

• Redsigned guide on my website to take changes into account

Edit 09/10/2026:

Version 2 of the Trim Wheel Pro has been released. Download the v2 files now.

Note: To upgrade from the earlier version, you only need to print version 2 of the base, version 2 of the lid, and version 2 of the tensioner. Everything else, all other prints, can remain the same as before. All the electronics, and even the code, can remain unchanged. It's just a straight swap.

Some of the new features include:

• A front‑mounted tension screw so you don't need to hunt around behind the device to tension the wheel.

• A reduced overall footprint.

• A trim wheel that protrudes a bit further, giving you more purchase if needed.

The assembly guide for this has also been updated. Please take a look at Trim Wheel Pro Assembly Guide

 Enjoy!
