Lucky the Leprechaun

If you have the proper filament colors, no painting is needed.

The assembled model is 220mm tall with the Lucky Charms rainbow. An optional standard rainbow is included, which results in a shorter model being179mm tall.

During QA, Benoit, also printed a copy of the full model at 145%, 336mm tall, and felt that the overall printing and assembly experience was 'easier' than the posted size.

Please read This model as well as most of my models are best enjoyed as 'projects'. Take the time to read the writeup for very helpful printing and assembly tips.

Enjoy!

Special shoutout to maker Benoît Lussier for providing full QA printing and quality feedback.

An extra shoutout to maker LTDInvestments, David Waugh, for providing an additional QA using his Anycubic machines.

Printing and assembly tips

Printing tips

Options:

Use either the rainbow files with the lucky_charms words to make the model look like the cereal box (with cereal box rainbow colors), or just use the rainbow_x files for a generic Leprechaun and a rainbow with standard colors.

The four swirl parts that are under the 'Y' can be loaded together for multi-material printing. Printing them separately (at the size posted) and attaching them is possible, but difficult due to their posted size.

1 - Supports ARE required on three parts.

*supports: default organic/tree supports

jacket

head

hand_right and hand_left (supports themselves are not needed but are used to stabilize the printing of the hands. I used 50deg angle supports in addition to rafts as noted below. I also removed the option in Bambu Slicer to ignore small overhangs.

2 - There are some pieces that may need brims or rafts, use your discretion. When setting up my prints I prefer to be conservative to ensure the least chance of a print failure, especially since the base of many parts are hidden when inserted into another part. Rafts also ensure that the first layer of small parts will have a better fit for my models.

*I used rafts on:

hand_right

hand_left

eye_blacks

if you have any bed adhesion issue with the rainbow parts, just add a 3-layer raft

*I used a brim on:

legs

jacket

3 - If you are concerned about seams, pay attention to the following parts to ensure the seams are located in the back:

pants

hat_top

hat_middle

4 - During QA it was highlighted that the scarf might print better with wall generation set to Classic instead of Arachne (which is set by default in the Prusa Slicer). I still do not understand why, but am adding this for completeness.

5 - When removing parts from the printer bed, it's a VERY good idea to place left/right parts into separate containers to help with the assembly process. Sometimes the difference between the left and right parts is very small but it is still worth keeping track of them and assembling them in their proper place.

Assembly tips:

1 - Take your time gluing the model together and enjoy the process. Give some thought into which parts to glue together as groups and then gluing the groups together. Let the glue for each group set completely before combining groups.

2 - I used 3D Gloop (strong fast drying) and E6000 (tacky slow drying) glues to put this model together. For both glues using a smaller amount is usually better than more glue.

3 - important for all my models, be sure to dry fit all parts before gluing.

4 - For this model I suggest:

Glue the parts in from the base through the jacket and scarf (without the hands). Care should be taken not to attach the pants backwards on the legs.

Glue the head/hat separately from the rest of the model.

Glue the head/hat to the body only once everything is fully set.

Again, waiting for the glue to set, the hands can then be glued into the jacket, keeping the dents for the rainbow straight across (dry fitting can be done here).

The rainbow is also glued together separately (there is a notch in the rainbow for the words), keeping the bottom of the rainbow even across the two sides.

Glue the rainbow to the hands and prop it up until dry.

*The bits can be glued at any time to the rainbow. There are no dents/pins so just approximate their position based the assembly diagram

5 - Refer to the assembly diagrams in the pictures section as well as the uploaded pictures for putting the model together. The model is meant to be glued.

Do not hesitate to ask questions, feedback is essential to making better models.
