Furniture fittings1

[babaroga]

This is my first post on forum. I am folowing FreeCAD for years and using it actively for past two years.

As R&D manager in my company, I am making lot of prototypes. For one of them, lead time for fittings was too long, so I made them by myself.
It is used for "butterfly" tabletops. I draw it and 3D print from one piece. It worked perfectly.

I used FreeCAD 0.17 from Github on Ubuntu 16.04.

Here is some screenshots and FreeCAD file. Maybe someone will find it useful.

Welcome! Nice work.

[bernd]

Would you share the file too?

@bernd

look at attacment there is a file named Sarnir.fcstd

I missed this somehow. How did the fitting the pieces together worked out. The "noses" did neither break nor squeeze?

It prints all in place, no need to attach the peaces afterwords, my test printed a bit fat, so i had to use quite a bit of force to brake the peaces free. Strong tight usable part, with no slop

Nice model, and first post. Welcome to the forum

Hello.

Nice part, thanks for sharing.
One "technical" question ...

To save time/material would it make sense to add a pocket in the middle of each "flange" on the backside
or setting the filling degree to 80% or less when 3D-printing ?

I guess, but there are so many variables when dealing with 3d-printing that there is generally no one correct answer, kind of like it is with FreeCAD. It all depends on a lot of variables where some of them are:

What is the part to be used for
Material old, new, brand, type of plastic.
Printer how well does it print on different speeds, is it properly calibrated.
Software etc.

I guess I would rather sett innfill to some lower value rather than making a pocket if your concern is soly time and material. I used ABS 20% infill and 3 0,25 mm external layers and I can not brake the part with my hands if my life depended on it.

Hello,

I am on vacation so slow on answer.
I printed it with ABS, 3 solid layers top/bottom, 3 perimeters, 0,5 mm nozzle and 0,2 mm layer height.
Infill was 15% rectilinear.
Everything was sliced with slic3r.

Distance between moving parts is 0,2 mm. I printed it with nozzle on 215 degrees to prevent too much sticking of parts.

Material used was some low quality chinese ABS. It was not wery hard to break this pieces, but i have very well calibrated printer.

I will also post drawings of whole table. It is also made in freecad.
