flux syringe plunger guide
thingiverse
I redesigned the plunger mechanism for those flux syringes, which was prone to wobbling and falling out. To address this issue, I created a guide that ensures the plunger stays securely in place. The guide is made from PET plastic, so it won't break off when handled. You can find the original flux syringe on eBay here: http://www.ebay.com/itm/272414653381 When printing, make sure to orient the object with the slot facing downwards. Support structures are not needed for this design.
