Bolts and Nuts for BLOMFLUGA IKEA and Hapo Workbench

When playing with my children I found that there weren’t enough nuts and bolts in the BLOMFLUGA IKEA set so I made a few in Onshape. 

To make the flanged bolt printable I split it up in two parts. These can be screwed together with ANSI standard tread so no need for supports. After screwing these together it's almost impossible to separate them so the parts should be child safe when printing in PETG. (But when in doubt that your clearance is too large it's better to glue them in place just to be sure.)

I've added three types of bolts. 

• Standard: 40mm
• Large: 65mm
• Medium: 25mm
• Small: 18mm

The standard and large sizes fit 3 and 5 flanged nuts (13mm) respectively. 

The Small one is 18mm and is perfect for securing a Beam to a nutblock (another model coming soon)

The Medium bolt is great for escuring 2 Beams together with a nut or to a nutblock while still having enough clearance for all other holes.

Most other parts of this set can already be found online:
