Toy Crane Grab

thingiverse

Update: Tolerances reviewed, Fusion360 file included. Feel free to improve or offer advice; I'm open to feedback as a first-time Fusion360 user. This design is my inaugural attempt at Fusion360. My son received an impressive rc toy crane with a hook and excavator for Christmas, prompting me to contribute some parts by designing a crane grab. In this design, I incorporated a printed spring; however, it's essential to use an alternative like the Vaterra spring soft/yellow 18x25 mm 2 pcs VTR233008. You'll need some m1.6 or m2 12-14mm screws or bolts (depending on your printer's accuracy). The required parts include four Arms and four "Verbinder. Assembly: Attach the Spring to the part „Aufhängung" and push part „Aufhängung2“ on top with reasonable force. I used an alligator wrench; afterwards, glue "Aufhängung3" on top. I printed this model before adding some tolerance, and it still worked, even with a somewhat okay plastic spring. This is work in progress!!
