About this 3D model
Used this to hold the toothbrush with my printer workstation, took the design for 3 brushes and modified for 1 brush - which is all I need to clean my filament drive gears. The holder can be fitted using the Countersunk screw holes, and /or by double sided tape. The toothbrush is held by the neck and is very secure in the holder.
