The support that this design is based on, I have printed on another smaller skadis and holding smaller things and it works fine. For another larger one that had to hold more weight I thought it wouldn't be enough. I had the problem of not being able to drill the wall, so I modified the file by adding a support under the table. It is designed for a 30mm table. If it is wider it may be just right.
It is printed in PLA.
