Mini Plastic Roll Holder

thingiverse

For Printrbot Jr owners, I designed a smaller spool holder as most standard versions are too large. Key features include two 3mm holes for wall suspension using screws, nails or thumb-tacks, and a 1/3" rod to expand the holding area. To print successfully, set speed settings to 20 mm/s with solid infill at 32 mm/s, bottom layer ratio at 1, nozzle diameter at 0.6, infill density between 0.1 and 0.3, and travel at 68 mm/s. A good fan is necessary to prevent bending or morphing due to insufficient cooling. Give it a try!
