This is a simple remix of the filament winder alignment guide. it reduces to travel of the filament guide from 55mm to 45mm to correct for common generic spool widths. It was done in Studio using the cut, scale and assembly view tools. i simply sectioned the model into 3 parts, reduce to y axis of the middle segment by 10mm, added a 5mm disk with a hole cut out to the gear side shaft, and reassembled the moddle on the horizontal plane. then rotated it back to vertical and viola.
