Easter Egg Dispenser Bunny

cults3d

The Happy Hopper is a delightful and decorative easy-to-print design perfect for the Easter season. The Bunny boasts a 'flip-top' head so you can load mini chocolate Easter Eggs into an internal channel that runs around the back and out the bottom at the front. A 'stop' is designed in at the bottom to hold the Easter Eggs from rolling straight through so they can be 'dispensed' one at a time. When the presented Easter Egg is removed, the rest shuffle down the internal channel so the next is ready to be dispensed... At standard scale, he dispenser measures 150mm x 105mmx 35mm and will take mini chocolate Easter Eggs measuring up to 28mm x 22mm (The channel at standard size measures 30mm x 23.5mm allowing 1.5 to 2mm rolling clearance). If you have a large enough build plate, the design can be scaled up uniformly to accept larger Easter Eggs. TIP: Please measure the Easter Eggs to be dispensed 'before' printing to ensure they will roll freely in the internal channel. If not, scale up to suit (Calculate the increase required including allowing for rolling clearance). Make sure you roll your Easter Eggs in sideways so they roll through the internal channel. You may need to hold the first egg in (bottom egg) during loading otherwise following eggs being loaded may have enough momentum to knock the previously loaded eggs out (i.e. dispense them all at once). Before loading your Easter Eggs, check the internal channel is free of print debris and as smooth as possible so the Easter Eggs inside can roll down with the minimum possible resistance. A well-printed dispenser should have no/very few printing imperfections affecting the channel... but if you have some cut them away or sand smooth. Removing / dispensing Easter Eggs is easy... just gently remove the available egg. The remaining eggs inside will move down a space. Please note that removing eggs slowly / gently will ensure the remaining eggs inside cannot gain enough momentum to roll down and jump the retaining ridge / stop at the end of the channel (i.e. The retaining ridge could have been made bigger / taller but this makes the eggs harder to remove... so it is a trade-off between easy to remove eggs and eggs being well held in place). This is purely a fun Easter thing. It has been designed to be an easy one-piece print with two components. The clearances applied are intentionally loose so it should print well regardless of the slicing app or machine used (as not all slicing apps or machines produce the same results). The notch at the front side of the joint is purely for alignment purposes to help ensure the head sits straight in its lowered position. Please note that the file has been updated in 2019 to strengthen the head / body linking pin as some people reported this part breaking when removing the print from the build plate or in use. It is still 3D printed plastic and a thin area but is stronger. 2-PART VERSION: Lots of people with machines with small build plates asked for a way to print this design. For this reason, two additional .stl's have been provided which allow the body and head to be printed separately then slotted together so the bunnies' head flips open/closed as usual. Please download the 2-part - A/B stl's for this requirement. Please also note that this version has not been test-printed... but it should be fine as this is a minor revision to the original one-piece version which prints well every time. Great fun... print in your choice of color/s and make sure you have plenty mini Easter Eggs on hand. The hard part is keeping the Happy Hopper stocked with eggs!
