Wall Mounted Roll-Up Green Screen

thingiverse

I couldn't find any complete designs on here, so I cobbled together several different files and made some changes to come up with this roll up green screen for my office. Obviously this will work the same for any fabric backdrop. Print: 2x Spacer 2x 608 Bearing Holder 1x Upper Pulley 2x Lower Pulley Pieces Materials Needed: -Green Screen -Large Dowel Rod -1/4" threaded rod & 1/4" nuts -3/16" drill bit -2 608zz Bearings -a few misc wood/decking screws -12ft beaded pull chain To put it together. . .Install Bearings in Printed Bearing holders. Slide Green Screen onto Wood Dowel Rod, and attach. I used small screws, but upholstery tacks, staples, etc will work. Just need to make sure the screen doesn't spin on the dowel rod when you try to roll it up. Drill 3/16" hole in the center of each side of the wooden dowel rod. (Make sure it's a centered as possible or it will wobble, but should still work fine either way) Screw in 1/4" threaded rod into each side. Add spacers and slide the bearing assembly onto each side. Add nuts inside and outside of bearing to secure/align assembly. Install Pulley outside of the bearing on one end of the assembly. Add nut on either side to help secure pulley to the 1/4" rod. Mount it to the wall, then drop chain over the pulley and install lower pulley assembly to tension the chain. Then enjoy being able to quickly roll-up your backdrop when not in use. Bearing Holder was from Bemcmullin: https://www.thingiverse.com/thing:3153213 Lower Chain Pulley is from lundiplutzmus: https://www.thingiverse.com/thing:2836936 The Upper Pulley I remixed from Ratfink's original design: https://www.thingiverse.com/thing:70179 Overall this works pretty well. The 1/4" threaded rod is difficult to get perfectly straight, but with the bearings it's still quite easy to roll up & down. The only other thing I've thought about adding is a little weight to the bottom of the screen so that it rolls up straighter and doesn't get offset a little.
