Sliding Door Guide

I had a sliding door guide fail after a couple of decades of use.  I had no idea how or where to get a replacement.  I gathered together all the broken bits I could find, measured them, and made a replacement model for 3D printing.

The first pic shows what I recovered of the broken bits and the newly printed part alongside it.  I added a few strength-enhancing fillets that the original model was missing.  Hopefully it'll be good for another 20 or 30 years.

Printing

I think I used 16 perimeters to completely fill the model.  I wanted 100% fill and rather than use "100% rectilinear " as the fill - I just use far too many perimeters to fill the model that way.  The resulting part feels quite strong.

I also used PETG-CF - because that's what my printer was loaded with and I was too lazy to swap it out for anything else.  That being said, I don't think the filament choice is critical in this instance.  I'm sure it would be just as good printed in PLA, PETG, ASA/ABS.  I reckon just print it with what's in your printer (provided the colour is acceptable).  No supports are necessary.

Print the model in the orientation as the file opens.  There's no need to flip/rotate at all.  Printing in the orientation as the model is presented ensures that the potential layer adhesion weaknesses are in the least problematic direction.
