My first Project in designing a 3D printable Part.

I was going for a Bauhaus design ( I like the look of that and it is easy to model)

Designed in FreeCAD. If you want the files to customize the model just ask!

this model is designed to be printed in Vase mode and to be filled with Gipsum / plaster of Paris etc.

Filament is expensive and it takes a whole lot of time to print heavy objects. A kitchen roll holder needs to be heavy though. The model worked better than expected. Looks and feels like a fully solid object when filled! Well it actually is!

When Printing this make sure you have 2 or 3 bottom layers. You will need them when Filling the Model! I am not sure if it is necessary to do so but I used a Brim. The surface on the bottom should be big enough to hold on on its own though.

First and foremost:

You print the base in Vase mode following the guidelines in the summary.

Leave the brim on while filling the model

Things you will need:

-A flat surface

-Plaster

-Water

-a mixing bowl

-a funnel (should be a sturdy one)

-a vibrating implement of sorts ( I'll let you figure that one out by yourselves)

Prepare everything you can beforehand.

Make a slightly more watery version of plaster (only a few ml more should do it) than the package sais. Use the coldest water you can get so you have enough time to fill the Model. mix it well an quick.

Now move FAST. Add the Plaster through the funnel using the vibrating implement to make the plaster less viscous and make it flow though the funnel. Don't forget to use that thing on the model to eliminate Air bubbles throughout.

The bottom of the model will bow out due to the pressure. Once the plaster line is about 20-40 mm (1-1.5 inches) from the top press the model on the surface (you can grab the Stock surprisingly strongly when applying pressure all the way around). You will have to make it flat.Overflow might happen.

Now prepare to stand there for a few minutes pressing down. Once it firms up you can still easily get rid of the overflow. and cut away the excess.

It takes about 1 or 2 weeks to fully cure. A few days after you cast the model you can put it on a Radiator to drive off the excess water. After it has fully cured print out the top ( I used 40 % infill ... overkill I know but i wanted it to feel as solid as possible) and glue it on.
