I wanted to modeled a Heart Shape Box for an 0.6 nozzle and Timberfill (wood fibre infused PLA). Out came this!
The clearing between the lid and the bottom is 0.3mm. The friction works perfect for my Setup, but depending on your Nozzle and material this may be too loose.
Adjusting the Flow rate in small amounts works wonders here!
The author marked this model as their own original creation.
