I am restoring an old Craftsman bandsaw for our MenzShed but the blade guides are missing and no longer available. I thought of trying to design and cut replacements on my S3 but dimensions would be a bit hit and miss with no pattern.
I have found a file on Thingiverse where the contributor has designed and produced a version on a 3d printer and has made the STL and Sketchup files available for download. He has installed them and they work fine so design must be close to original,…https://www.thingiverse.com/thing:2777028/files
I have tried to download the STL to convert to a vector file to cut some from HDPE but when I try to open the file I get a message:
“Invalid Public Key Security Object file
This file is invalid for use as the following: Certificate Trust List”
A look at the file in preview it seems to be the Trust Certificate and not the actual STL file.
Any idea what I may be doing wrong and how I can get the STL?
