ATTENTION: This model was created for the screws and nuts to be added separately afterwards.
It is better to print with PETG, as PLA would melt around the screws because they would get hotter and more quickly.
Even though it was measured during modeling, I found that printing it in 101% scale was better, it did not get stuck and could spin around both easily and without coming off.
I decided to model it with the screw holes being open from the inside to let the screws into the rail, thus making it more stable and durable.
The author marked this model as their own original creation.
