Easy Print No Support Modular Candy Dispenser

thingiverse

I set out to craft a dispenser that would print rapidly and require no supports, forcing me to rethink many components along the way. I am pleased with the outcome. It's designed to match a standard Mason jar used for canning, threaded accordingly. The parts should snap together securely, but I hot glued the jar coupler to the top to prevent it from coming loose. I didn't want the glass jar to fall off. I built everything modular so it could be easily modified to suit other needs or tastes. I included barrels that dispense just over the recommended serving size for plain and peanut M&M's. The plain ones dispense smoothly and reliably, but the peanut sometimes will jam at the top inside of the jar. If I made another one, I might create something to sit inside the jar like a cross or cone to keep them from clumping together. When disassembling it, take care not to snap off the pegs if it comes apart at an angle. These were printed with no supports at all at 15% infill for everything except the handle, which I did at 50% to ensure it wouldn't warp or shear off over time. Layer heights are 0.12mm. The parts were printed in the orientations shown in the photo of all the parts laid out. A video of it in action can be found here: https://youtu.be/EA6aCI_IfXQ My source model was made in Tinkercad and can be found here: https://www.tinkercad.com/things/dAwKPglaaga Please share any prints or remixes! I have ideas for other handles, barrels, and couplers for different containers in the future. I learned a lot making this model and have some great new techniques to use going forward. UPDATED 10/21/18 I added a file called Dispenser-jar-coupler-small-square.stl. The part where the coupler meets the box is .5mm smaller, making it a bit looser for those who were having trouble getting them to fit. Be sure to glue this down! I have also left a copy of this part separate in pink inside the Tinkercad document, so it can be resized as needed and then grouped with everything else in pink (and grey).
