Updated gift card 1 doesn't need any support anymore.
Print The updated gift cards "Updated gift card 1 V2" and "Updated gift card 2 V2". These cards contain the following updates:
- The windup shaft is modified to be printed without support, so the whole card doesn't need support anymore.
- extra crosspiece in the front of the frame for extra rigidity.
- extra spacers to keep the gears in place.
- modified rear axle for less side to side play.
- slot cut out in the spring for a better fitment around the shaft.
- added some different kind of springs seperatly so you can experiment which one works the best for you.
The spacers have bumps on the side. The amount of bumps determins it's place from front to back. Spacer 1 (1 bump) goes between the spring and the gripper ring. Spacer 2 (2 bumps) goes on the first gear shaft. Spacer 3 (3 bumps) goes on the second gear shaft. Spacer 4 (4 bumps) goes between the small gear and the frame on the rear axel.
This wind-up car gift card is the ideal present for your friends and family. Everything on this wind-up toy car is 3D-printable, the spring, shafts, gears, wheels, everything! There are no other parts/tools necessary except for your 3D-printer and some filament (although a small hamer and a knife would be usefull but not necessary).You can make you friends happy by giving them a nice present and at the same time you can show them what is possible with 3D-printing. I created an easy instruction manual to add to the realism of building a real model kit ;-)
You can chose to print the 2 gift cards to give them to someone as a gift or to just assemble it yourself and relive some of your childhood ;-). You can also print all the parts seperatly so you don't have to remove any card material.
The whole car can be assembled without the need for any glue. The print time for gift card 1 (the one with the most parts) is about 4 hours. The print time for gift card 2 (the one with the wheels) is about 2 hours. I decided to print them with 100 percent infill because there wasn't that much of a difference with 25 percent infill, the print time was about the same. Another reason for 100 percent infill is that the spring is being printed better.
I tried to arrange all the parts on the card so that it is possible to print the 2 cards in 2 different collors and still look good (eg: not 1 wheel on one card and the 3 others on the other card).
