Hi Aardvark, happy to hear from you again!

Great to hear my STL thumbnails work! Just in case you didn’t know: You can adjust the colors and the viewing angle via registry if you don’t like the...

I just fixed a small error with the Windows Registry that prevented the thumbnails from running under some circumstances. If anyone of you had trouble with the thumbnails before, it?s a good time to...

Hi! You may remember me from Papa's Best STL Viewer ...

I've finished my Explorer extension that shows preview thumbnails for STL files. No need to open anything, all models display right in the...

Hi Emil,

Thank you for the SmartScreen hint! It’s safe to disregard it.

SmartScreen tracks the number of downloads and it warns automatically if a file is not downloaded very often. I just...

I updated the viewer, and it now renders the back sides of polygons as well. (A user requested it and I think he was totally right about it.) If you missed that feature as well, update at...

Thank you, aardvark – I’m so happy to read your feedback! :) If you want to spend me a dime, there is now a Donate page on my site!

I also added the ability to merge multiple STLs into a single...

I’ve seen this coming – I use virustotal to check my programs before uploading: https://www.virustotal.com/#/file/4610a7f46d23da3b31ae6eedc426f11c1c096edb64b73858c800eb6f4c4a2df5/detection

New version of Papa’s Best STL Viewer with many bugfixes :) https://papas-best.com/stlviewer_en

You can now also reach the solid/wireframe/hidden line rendering via F5/F6/F7. (I personally prefer...

cgimark, wireframe rendering and hidden line is implemented: https://papas-best.com/stlviewer_en (in the “View” menu). Many other bugs have been fixed as well. (The update is very new, so malware...

cgimark, here’s a build with wireframe rendering enabled (hidden lines will take some more time because I need new shaders):

Setup:

64-bit:...

Very high chance – I’m working on it :)

Thank you for testing! I have contacted AVG (yesterday) and Avast (today), but I suspect they won’t update their databases until after Christmas :(

I’m sorry for that; I will contact them...

Hi again!

I improved the STL viewer:

you can easily fix a file’s rotation by selecting Y Up or Z Up in the right panel
fixed UI problems with colors and zoom
download:...

I released another update. You’re invited to try it! http://papas-best.com/stlviewer_en

- fixes zoom direction not being saved
- fixes a few crashes
- fixes some UI glitches (sizing, high-DPI...

aardvark, I’m very glad to hear that. Spread the word! :)

mjf55, AVG answered:I.e. please update in 24 hours, and if the problem persists, you can take screenshots and I’ll forward them to AVG for...

I’m sorry to hear that!

I contacted AVG about the issue and I hope they resolve it. Is your AVG updated? According to virustotal, it should now be fine:...

Fixed, and the AV suites finally stopped classifying my 32-bit build as malware :) Here it is:
Setup: http://papas-best.com/downloads/stlviewer/stable/x86/Papas%20Best%20STL%20Viewer.msi
Portable:...

I’m very glad to hear that, thanks! I’ll fix the bug, of course.

You mean like, if you right-click an STL, you have a “preview” option in the menu, and selecting it opens the viewer? That’s...

Thanks for testing that!

Yup, that’s the reason that I didn’t upload the 32-bit version yet :( While virustotal reports the 64-bit versions clean (here and here – even for AVG), some anti-virus...

Hi fellow makers!

I often need to browse folders full of STLs, but the regular fabbing tools are just too cumbersome and slow for that. So I wrote a very fast STL viewer which allows to skip to...
