How do trains turn. This print demonstrates how. The model is similar to that used in the attached video https://www.youtube.com/watch?v=HeDuGWNTDPY&t=96s

Extra gear

• glue
• sand paper (i used 120 grit)

What to print

• 2x track legs
• 2x wheels
• 2x track
• 1x axle

Notes

• I used white filament so the glue cannot be seen
• when rolling the wheels down place the wheels straight on the track. It you don't it can derail

No

No

I used 120 grit

• Sand where tracks join to remove elephants foot for a flush connectiong when glueing.
• Sand wheels where it meets rail
• Sand rail where wheels meet rail. Wheels don't just sit on very top of rail so sand the whole arch

I used super glue

• Glue axle to wheels
• Glue tracks together
• Glue track legs
