caterpillar scraper, earth mover

thingiverse

I made this gift for my dad last Christmas. He stopped driving these machines a few years ago after retiring. I found the original drawing online, but it wasn't printable, so I drew it again to make it print-ready. You can attach the front and back together with glue or drill out the hinge area and add a rod to make it foldable. The axles are made from aluminum tubing that fits snugly into the wheel hubs. The scraper body is printed in bright yellow, while the windows and windshields are transparent blue. Black would also look great, I think. The group of scraper parts includes printing two sets: round ones for hiding holes if you drill out the hinge area, and other parts to fill thin areas at the back. Hopefully, that makes sense. This project needs plenty of support, but it's a hassle to remove it when finished. Despite this, the final result looks stunning. I forgot to take a picture before giving it to him, so I'll ask my dad to send me one and post it when I can.
