Hexagon blocking board 5,5 cm

Blocking board for crochet hexagons! I'm making a blanket and need 59 hexagons of the same size. 

The holes for the pins in the corners are 55 mm (5,5 cm / 2,165 inch) apart. 

The holes are 10 mm (0,39 inch) deep and 3 mm (0,118 inch) wide. 

I use metal pins of 2,5 mm width. (That is a bit loose, but very usable, especially if you print the blocking board twice and put one on top.) 

The pins are made from: https://www.amazon.nl/gp/aw/d/B0C1Z4Z66D?psc=1&ref=ppx_pop_mob_b_asin_image 

(Cut in 5 pieces of 6 cm; I can block 8 hexagons simultaniously.) 

I added the .step file so you can edit the size of the blocking board for your project.
