Bubble Laminating Roller

I didn't want to pay $15+ for a Fiberglass Bubble Roller so I quickly design & made this. It's a simple but cost-effective model. Easy to assemble, 2 printed parts which you use 2xM3 25mm or 30mm screws. I used the default Kobra3 'Normal' settings with Infill set to 'Solid Infill Every = 1'. For the Roller Handle, I enable 'Grid' Support & the Roller had 'Organic' Support. Have to be very careful & gentle when breaking the Organic support away from the Roller so, it doesn't break the spikes. There is 2 different size Rollers, the larger size has a better fitment.
