Making Mendel90, Last week I entered the RepRap 3D printing...

Last week I entered the RepRap 3D printing competition (purely for fun) and came first in the judging. This was my entry.

My prize for winning was to choose the subject for the next competition so, naturally enough, I chose a puzzle.

There were several excellent entries but this was Greg Frost’s winning print.

His great suggestions for successfully printing at low layer heights have inspired me to have another go myself. Here’s a print I’m doing at 0.15 mm layer height using a honeycomb fill every 2 layers. So far it seems to be working very well.
