Impossible Passthrough Bowling Pin

Hello!

Yet another impossible object idea I got recently.

This is a perfect gift for a bowling fan!

This model is print in place and doesn't require 2 parts.

You can scale it up, but I do not reccomend scaling it down because of the following:

The 6 bottom pillars can be very unstable without a brim and it can lead to print failiures.

Please take note that a brim is mandatory and that you will have to trim the brimm off with a scalper to get a clean passthrough.

This is because of the part where the main body of the pin connects to the first “pillars”, since a bowling pin is thinner on the bottom than in the middle.

NOTE:

If you want a single colour print just disable one of the colours.

If you want to print both pieces separately, use “Split to objects”, you will have to recolour the pins by using the Colour by layer command and setting the height to 3.

Print settings:

• 0.4 mm nozzle
• 0.2mm layer height
• IMPORTANT: INITIAL LAYER HEIGHT 0.3mm (this is to achieve better adhesion)
• outer brim with 0.05mm brim-object gap
• prime tower can be as big as you want it to be
• i reccomend printing in wihte and red PLA
