MantRa Rays Lampshade

Prints (0)

Description

This lampshade is inspired by a form study of the manta ray I did using Grasshopper Parametric modelling. 

It is printed in two parts, one short print and one long one and the two are then carefully superglued together. The reason for the two parts is to provide a larger flat surface area so the project can stick to the build plate better. I found it quite a challenging print as it does not have supports or infill, I felt these would spoil the print somewhat. I had to do one or two short test prints before I found settings that gave acceptable results. 

Once glued together the lampshade is complete, a bulb holder can be attached to the inbuilt bracket and held in final position with a cable tie. Make sure the bulb glass itself does not touch any part of the PLA during use and is at least an inch away so that any heat the bulb produces does not conduct into and melt the PLA, it might cause a fire. Maximum of 40 watt bulb is recommended, or use a cool temperature LED or low energy bulb.

Layer Height - 0.20mm

Initial Layer Height - 0.15mm
