Introduction: How I Fix a Hole in a Wall With Friable Plaster ...

I live in an old House with friable plaster on all walls and I have always problems to fix something on the walls. One morning I woke up and my blind layed on the ground and I had a hole(60x25x20) in the wall where the blind was fixed ...

100 years ago they used pieces of wood to fix blinds, the orginal one was broken and I usually haven't pieces of wood in my flat ...

But I have a 3D printer :-)

So I created a block which fits the hole, the sides are ripply to increase the friction and a lot of screwholes to fix my blind one the right position ...

... problem solved ...

Step 1: Create the Replacement Block in Fusion 360 and Print It ...

I measured the size of the hole, it was circa 60x25x20.

So I created a block wih a size of 55x20x20, I sketched 8 circles on top on every side ...

I added every uneven circle to the block and I removed every even circle...

I added 27 holes on front sides which fits to my screw size ...

After that I printed this block ...

Step 2: Plaster the Block Into the Hole ...

I mixed plaster and filled the half hole ...

After that I put the block into the hole and removed surplus plaster ...

I waited one day to let the plaster dry ...

I fixed the blind on the block ...

Great idea, I wish i had a 3D printer to try this out. If you measured the depth, you could glue the rear side with heavy duty construction adhesive. It would probably be extra strong.

you could do the same with a block of wood and conventional tools
