Prototype cost

I decided to create this section so that those who will do the same with their projects will know how much it costs.
___

3d printed case (2 pcs) - v1 - just to get idea about general size of the device - €15

Delivery + taxes for these cases - €26

___

3d printed case (2 pcs) - v2 - testing specific material - €7

Delivery - €35

Taxes (I probably need to find different logistics company) - €35
___

PCB manufacturing (5 pcs) - 17

PCB assembly (1 pcs) - 55

PCB Delivery + Taxes - 33

___


Grand total ~ €223

Important notes:

  • this values does not include labour cost
  • I will 100% go through few more rounds of 3d printing
  • I will 100% go through few more rounds of PCB prototyping 
  • PCB assembly is made in PRC, same PCB assembly in EU (Aisler) estimated at around 400

    I re-evaluated the cost of 3d printing/delivery/taxes and ordered myself basic 3d printer.

    All 3d printed parts that I've ordered cost me ~ 115.
    Printed I've ordered was ~ 200. 
    Most probably it will be used for prototyping not for mass production, but even that can help cut costs.

    Second iteration of the 3D-printed case, I think I’ve finally decided on the overall size and look.

    I will rework top part since I want this connection to be secure and reliable but it will do for now.
