BeamCase - Nut Positioner

This nut positioner keeps flat square nuts (DIN 562) in their position, so they do not slide around in the Makerbeam XL profile.

When adding brackets and other parts to your BeamCase, (or other projects using Makerbeam XL profiles) keeping the nuts from sliding makes things much easier. Thats why I developed this small 3d print the nut positioner. 

The plastic goes around a thin square M3 nut (DIN 562) and has a friction fit within the profile, which keeps the nut from sliding around. 
 

Required Hardware:

Nuts: 
square M3 nuts DIN 562 (1.7-1.8mm thick)
(I am located in Germany and buy them here)

Print Instructions:

In order to get a good friction fit you might need to play around with scaling a bit, as the tolerances are very tight and each printer is slightly different. 

Do NOT print this model in PLA, as it creeps under constant load, so it will not keep the friction fit, instead use something like PETg or ABS. Ideally compensate for shrinkage. 

I adjust for ABS shrinkage by scaling the model to 100.5% (Bambu Lab P1S and Sunlu ABS) , but it depends on the filament and printer and print speed. (a print file for this exact combination can be downloaded here)
 

Alternative:

If you do not have access to the specific square nuts, the you can use standard m3 nuts and 5mm long scrub screws. this way you can secure a nut with a scrub screw in front and behind the nut you want top keep in place. A demonstration of this is visible in the last picture.
