8.5mm MDF board filament passthrough

There were a lot of similar models of what I wanted to do, but none was exactly what I needed. Many were too long intended for LACK tables, many were too short and intended for plastic boxes… So here is another solution. It is designed for 8.5mm to 10mm thick boards.

Drill a 10mm hole, pass the top part through the drilled hole and tighten the nut. You could use a nº22 and a nº16 wrench to tighten them. Don't over do it.

After that, thread one or two PC4 M6 bowden fittings and the bowden tube.

One fitting should be more than enough but you have the choice to add another, although it's a bit tricky and you might need to trick its internal mechanism with another piece of tube to insert it.
