Nerf Rival Dueling Tree

thingiverse

Update 10/7/20: Printed and set up 4 paddles. They do seem to bounce off the opposite side when hit and return back to the original side. lol. I did add a small piece of open cell foam inside the lower swivel in between the bearings to add just a bit of friction. Which helps. But I think Increasing the tilt of the mount on the base will help also so the paddles need more force to bounce back, and this will also help the paddles come to a rest all the way forward. I added the Base 10deg file as an alternate. The original was only tilted 5 degrees. Update 10/5/20: Found one mistake with the L stem. Updated the file. The small step wasn't deep enough on the small 45 section to allow for proper assembly of the following stem. This is a dueling tree for the Nerf Rival series of blasters. It may work with others depending on the velocity of the projectiles. It was made modular so you can print and stack as many paddles as you want but should be done in sets of 2 with a minimum of 4 to make the game work correctly. First set the paddles alternating side to side on the stand. The object is to blast against an opponent. the first one to get all the paddles to the opponents side wins. Extra Items Needed: M6 x 16mm screws - 2 per section M6 x 20mm screw - 1 for first section to mount to base 608 bearings - 2 per section 8mm x 52mm shafts - 1 per section 3 misc screws - for base I printed all the pieces with a .6 nozzle at a .24 layer height to save on some print time. All pieces except the L stem do not need supports. I printed the L stem as the file shows for layer strength with a 5 row brim for added adhesion to the printer bed. The L stem and paddles were printed at 100% infill for strength. The rest were at 15 or 20%. I also opted to change colors half way through on the paddles, Red/Blue, so each team knows which paddles to blast. The fit into the upper swivel should be a snug slip fit to you can disassemble the unit if needed, or replace a paddle if needed. The press fit of the bearings should be snug but not to tight. The shafts should be tighter. I used my drill press to align and press them in. The base is meant to screw to a larger board or something else with some weight so it doesn't tip over. I will upload a video when I finish printing everything.
