„Black Widow“ Mobile - 3D Printed

A "Black Widow" in her web ... waiting for prey! ... a light breeze or a gentle blow will get the spider moving!

If you put the "Black Widow" installation between a light source and a wall, you can achieve very nice creepy effects. The right thing for Halloween! (see video). However, the light source must consist of only 1 light point. A light source consisting of several LEDs, does not work properly. 

Dimensions:

• H 190 mm
• W base 110 mm
• W net 183 mm

Files to print:

• base.stl
• spider.stl
• web.stl

Print Settings:

• Printer brands: Prusa, Flashforge
• Printer: MK3S / Mini / Finder
• Supports: No
• Resolution: 0,2
• Infill: 15%
• Filament brand: Prusa; ICE
• Filament color: Galaxy Black, Galaxy Silver; Romantic Red
• Filament material: PLA

Remark: As all parts are designed to fit very precisely, it may happen that you have to rework one or the other part a bit with sandpaper and/or cutter due to different dimensional accuracy of the printers and the different behavior of the filaments.

Attachments

To connect the 3 printed parts you need:

• 30 cm nylon thread Ø 0.25 mm (or less Ø)
• super glue

The spider web is printed very filigree (this is intended) and must therefore be very carefully released from the printing plate. 

The insertion of the spider web ring must be tried before gluing. It is very tightly dimensioned, which is intended. The width of the recess in the base is definitely 0.15 mm wider than the width of the spider web ring.

See also „Remark“ in the introduction!

In my case, it fits so well that gluing is not necessary at the moment!

To hang the spider in the spider web ring, there is a hole in the spider that goes vertically through the body.

Take a nylon thread Ø 0,25 or less, about 30cm long and make a multiple knot at one end. Then pass the thread from through the back of the spider to the front.

Take the spider with the thread inserted and pass the thread through the hole in the web ring from below.

Now you have to try to find the position of the spider in the center of the net. This is a bit fiddly and requires - as in my case - several attempts.

When the spider is hanging in the right position, you should try to find the resting position - parallel in the net. You can achieve this by lifting the thread. By turning the knot you can find the right position with a little patience.

I hope you had no problems with printing and assembling the mobile!

... and now have fun with the "BLACK WIDOW" mobile! Maybe you can also create some spooky effects - like in my video!
