A few weeks ago my Hapax had an accident which included a cheap digital microscop with a solid steel plate base, a cable, a height difference of ~one meter and a very clumsy me. 
I reached out to Squarp and they generously sent me a replacement cover
These are the steps it took to replace the broken one.
- gently pull on the 9 knobs to remove them
- use a Torx Tx6 screwdriver to remove all the black and silver screws from the front plate
- lift off the front plate
- Press from below against the broken screen cover, hot air helps with softening the glue but it took some effort
- Clean up the left over sticky mess (I also used some hand desinfectant as solvent - works better than alcohol as it does not evaporate as fast)
- small touch up (optional)
- remove protective film from the replacement part and carefully place it in position
- Before reassembly check for dust and fingerprints below the panels and on the screens
- screw the top plate back in place, put the knobs back on, check for clickyness - enjoy
Now back to re-arranging the studio, my final project for this year and I really want to get it done today 
Thanks to Squarp ro the part!
All the best for the new year,
Johannes
