Hit the Marble - Marble Castle

Hit The Marble - Marble Castle

At the end of a forecourt paved with old, sagging concrete slabs, an old brick castle tower rises into the air. At the foot of the castle lies an abandoned marble. A catapult arm resting on two old stones rises up in front of the castle, initially giving the impression that the marble can escape. However, there is something treacherous about the castle. Can you help the marble escape?

Improvement:

Some parts have been improved and the pictures may differ. The function is the same. Some tolerances have been tightened, which makes assembly a little more difficult, but provides more stability.

I reinforced the catapuilt arm and changed the structure a little to make it more stable.

Instructions:

With the spring-loaded catapult arm, the marble can be hurled into the path with skillful movements.
Hit the Marble is based on the well-known funfair attraction “Hit the Luca”. With or without a hammer, this little game is great fun for young and old.

Printable on a printing plate without AMS, the marble castle is ready in just under 5 hours. The small number of parts guarantees easy assembly.

The hammer can be printed with an additive part in the slicer with more infill to make the hammer head heavier. 
I printed the Hit the Marble on two plates to make the catapult arm and the track in wood look (brown).

A compression spring for the catapult arm is required (not mandatory). The dimensions fit a spring with the dimensions 7.0 x 32 x 0.8. The dimensions can also be adapted on request https://www.testberichte.de/pdb/JoV_ghl9R66xRyH09tog8w.html?utm_source=4442&utm_medium=tbw&utm_campaign=4&c=21246598785&g=162863942138&gad_source=1&gclid=EAIaIQobChMIxZaV8_jWigMVE7CDBx1b7gTpEAQYASABEgKq5vD_BwE.

Printing tips:

Print with the support structure tree. There are two files available. 
A One PLate Slicer file where all components can be printed on one plate (P1S). 
The other file contains two printing plates to print the catapult arm and the track in brown (tree like).

After printing, remove the supports and assemble the track as follows.

Solution To the Marble Problem:

The marble does not always roll back into the tower. I'm working on a solution. 

After a few tests and tips from testers, I decided to leave it as it is, as the ball rolls back with a skillful shot. Think of it as a game and a             challenge

Assembly:

1. Insert the Castle tower in the base plate (First insert one side and press down the other improved tolerances have been selected so that the tower is stable).

2. Insert the compression spring into the catapult arm.

3. Insert the catapult arm into the tower and place it on the brackets and push the compression spring in the base plate.

4. Push the catapultarm down and Slide the Catapult arm counterparts onto the brackets.

5. Adjust the catapultarm that it is in the middle of the Castle tower

6. Drop the marble into the Castle tower

7. First slide the marble run element into the top of the tower

Make sure that the marble run is pushed all the way down until it stops and rests fully on the tower

and then insert it into the hole on the side of the tower.

8. Slide the Castle Tower on the tower
