Hi there! I realized this product to ensure support for the spool of the filament.
Here 2 elements which are assembled to perform a rigid attachment on the Prusa i3 frame accompained by M6 screw and 2 M6 nuts.
The dimensions were chosen to be compatible with the frame of the Prusa i3.
In particular, as you can see in the pictures, for a frame with a section of about 41mm x 7mm.
I recommend a 30 % infill to ensure an appropriate resistance.
Please enjoy it.
