About this 3D model
The F-UP a up stand cradle for your F clamps to hold clamp upright for easy glue ups. Printing: They will need to be robust as there going to need to support the weight not just the clamp but also the project your gluing so I recommend 4 walls minimum and 25% infill with something like 3D honeycomb or 100% max strength. No Supports needed and i print with no brim on textured plate with no problems.
