Here's a fun, quick, simple print to brighten up the holidays. The design is clearly a bell, but it also references Renaissance architecture.

EASY PRINT If you just got your first 3D printer, this might not be the first thing you print, but it can be one of your earliest prints. Using the settings I recommend below, you should be able to print it with little difficulty.

COMMON PRINTING PROBLEMS Assuming you use the print settings I recommended below, here are some common problems and possible fixes:

• Mushy print: Reduce print temp.
• Comes off bed: Increase raft size. Reduce print speed.
• Print looks rough: Reduce print speed.
• Breaks during printing: Reduce print speed and print temperature. If you can, increase cooling.

PRINT TIME With my settings, it took about 3 hours.

PRINT SETTINGS Thickness

• Layer thickness: .15mm
• Wall thickness: 0.8mm. If you want to go thinner to reduce weight, consider using Cura's “alternate extra wall” option so it alternates between 0.4 and 0.8mm walls with each layer. That may prevent gaps in the print.
• Top/bottom thickness: 0.3mm

Infill This doesn't need any infill. Seriously.

Speed You'll want to use slow printer settings to that the print is accurate and to reduce chance the bell is pulled off the plate curing printing.

• Overall: 60mm/s
• Outer wall: 30mm/s
• Inner wall: 40mm/s
• Travel Speed: 65mm/sec

Build Plate Adhesion The first layer of the bell is just a thin circle. I've found that a thin (4mm extra margin) raft works well to provide bed adhesion. It also separates more cleanly than a brim for this model. The raft only adds about 10 minutes to the print time.

Supports I recommend printing with supports to ensure the roof of the bell prints cleanly. Ok, it doesn't show when it's hanging up, but I'm a perfectionist. With these settings, you'll only get supports where you need them.

• Support placement: Touching buildplate
• Support overhang angle: 71 degrees (this really is all you need)
• Support pattern: Gyroid
• Support wall line count: 1
• Support density: 15%
