This project used the original model <Mystery Machine of Southern IL.by Ramblin73 Apr 27, 2018M. Please show love by liking the original design, Thank you Ramblin73.
Print came out looking good. With my settings all above details came out great,, which is a testament to the good original design,
I enlarged the original file so all coins will fit the bank when printed a x1 file size. Bank includes the quick fit plug, key, key-storage box, standard plug, and tea-light plug to use it as a night lamp (Samyo Tea-light 30mm diameter x 25mm from Amazon).
See Bank2 in another of my posts for bank with rolling wheels. 2-7-2019.
If you have any questions or suggestions, please let me know. Thank you for looking. Enjoy!.
3D Best PLA
Printed at 210c/50c, must be a zero infill, recommend 2mm wall thickness all around, 5% support from bed under the model.
Used 50% infill with 3 wall layers for key and plugs. I use a 5 line skirt around the key for added bed adhesion .
I've included extra pictures to help describe the cleanup of the plug hole and internal stringing I had. You will need to cut out the caps printed internally over them because this is vase mode with top/bottom layers.
I used a partial round with sharp edged file to scribe around the hole and then pop out the caps. left a nice filed edge,
I had a lot of stringing in my print . I had retraction at 40mm/s and 8 mm. may want 10mm or more retraction to help keep the stringing down.
The original model had a center support beam in it and it stayed in this print. I also used rhe file to under scribe it on the two sides of the plug hole then used my cutters to cut them cleanly away.
The underside had some rough spots but very solid,
Used Tinkercad and Cura...in Tinkercad find Dadmezz, copy objects, select ungroup to see the construction steps.
