Wired anti bird spikes base (magnet friendly).

Info:

• created a base for pieces of wire, because:
  • wire is industrial standard for usual anti-bird spikes and wire spikes are much less visible from distance than anything printed, thus it is better to print only base and buy wire
  • this is suitable for up to ⌀ 1mm wire
• can be attached:
  • via magnets to metal things (window sill)
  • via nails to wooden constructions 

Print info:

• choose your size ("pigeon-spike-base-5x.stl" fits Prusa MK3/MK4 bed)
• choose filament
  • for outside use I recommend some material that can withstand high temperatures especially when on the sun and on metal window sill (like modified PLA for 110°C - e.g. https://www.aurapol.com/cz/pla-ht110  )
• do not print too fast, otherwise holes for wires may not be ideal and you can have problems later inserting them

Attachment

• choose attachment
  • nails? easy
    • model contains nail holes
  • magnets
    • model contains M3 and M4 thread holes
    • recommending neodymium magnets with surface protection against water
      • e.g. https://www.unimagnet.cz/neodymovy-kruhovy-magnet-10-7-3-5-mm-v-3-mm-m3-sila-1-6-kg-cerny_z1273/?&utm_source=notification&utm_medium=email&utm_campaign=order_create 
      • those are magnets for M3 bolts - with epoxy surface, for those 3mm high magnets I have used stainless steel M3 bolts high at least 6mm or better 8mm+
      • I have used 3 such magnets for every printed base (total magnetic power 1,6kg * 3 = 4,8kg) but also 2 such magnets would do the job fine

Assembly

• be sure to protect eyes if working with sharp wire
• the middle version ("5x" in the name) is constructed for 3*5 wire pieces = 15 pieces in total
  • I use usually wire cut to 34cm length - so it is about 5m of wire needed
  • but you can use less/more.
• catch every piece of wire in the middle with thin pliers (like a Prusa default in Prusa assembly kits) - see last picture
• insert 10 pieces from top side first (both ends of wire to 2 holes at once)
  • twist wires in fingers if it is stucked or even you can use pliers to force it go inside and then outside on the other side
  • remember to have narrow ends of the wire
• then bend all those to the side
• now insert remaining 5 from the bottom
• adjust directions/angles of wire

• happy printing and bird deterring
