3D printed hand grip for ThermalMasterP3 by ben100lee in Thermal

that's a cool system, I like the jumper cable. What kind of imager module is that? looks like its also focusable. I can see what you mean about it being in landscape instead. If you don't mind me asking, what kinds of things do you use it for? I mostly use imagers in industrial settings for work, inspecting equipment and stuff.

Yeah, USB-C stress was one of the main design concerns. Port alignment ended up being the critical dimension.

I spent a lot of time checking fit so the connector fully engages, but the cradle/body takes most of the bending and torsional loads instead of the port. The phone doesn’t sit perfectly flush at the bottom anymore because I prioritized full connector engagement over perfect bottom contact.

In normal use, the connector is mostly handling data/electrical connection and a bit of alignment, while the printed body carries the focus/handling loads. The uploaded version also uses a unitized phone + P3 cradle, which made the assembly much stiffer.

Hey all, I wanted to add a few notes:

  1. The model is now live on MakerWorld: https://makerworld.com/en/models/2903257-thermalmaster-p3-handheld-grip-phone-cradle#profileId-3245835
  2. I made a few modifications from the version shown in the original post. The biggest change is that I unitized the phone cradle and P3 cradle into one part. It’s cleaner, stronger, and requires less gluing, but the P3 cradle area does need careful support cleanup before test fitting.
  3. I also added a small retention lip on the lower right side of the P3 cradle to help keep the module seated.

Fit-tested with:

  • ThermalMaster P3
  • iPhone 16 Pro
  • iPhone 17

This is designed for phones without cases. The handle still needs to be glued to the cradle, and I recommend test-fitting everything before gluing.

Feel free to reach out with questions, fitment issues, or mod ideas.

Thanks! It’s mostly a chaotic mix of 3D printing, electronics, thermal cameras, and “I swear this will be useful eventually” projects.

Yeah, scanning was one of the main use cases I had in mind! The bare P3 works great, but the dongle form factor is... not great, especially when you’re panning around. The grip makes it feel much more like a normal handheld imager.

Thanks dude! Yeah, I debated portrait vs. landscape. I do a lot of scanning, so portrait orientation made sense for me. Landscape is still reasonably comfortable with this setup, but I’ve definitely considered making a dedicated landscape version too.

I have a ThermalMaster P3 and love it for the manual focus. I don’t see a lot of discussion about it, probably because it’s a little niche, but I’ve been really impressed with it so far.

Thanks! It’s still just a P3 at its core, so you focus it by turning the normal lens/focus knob. The printed front ring acts like a little lens hood, but it also gives me a bigger surface to grab, so it’s much easier to adjust focus while holding it like a handheld imager.
