Foldable Dart

This is a scaled-down version of the folding dart After scaling down the parts the pin strength was too low so I changed the raised plug on the pull rod to a hole for inserting a short piece of filament Each hole can be about 4-5 mm
After testing several times I found the support in the center was difficult to remove it needs to be trimmed with a knife Be careful not to cut your hand Experts can modify the profile themselves

The two holes on each pull rod are just right but other holes are not It might be a problem with my 3D Printer There's always one hole on each accessory that's a bit tight It can be trimmed with a utility knife
It's not easy to make It doesn't matter if you give a boost or not just please don't give a bad review it's quite disheartening
