IKEA TARNABY Replacement Lamp Shade & Other Variations

IKEA don't sell replacement glass lampshades for their common TÄRNABY table lamp, so this was my solution…

Original single walled vase mode print worked well but was a little flimsy so I decided to use a lattice vase mode technique I've been working on. The lattice drastically improves vase mode layer adhesion and part strength by sandwiching alternate layers together, plus it gives such a nice exterior finish. It is a little dimmer than the others but it is definitely my favourite of the three.

Here's a vase test I did with the same wall structure: https://www.printables.com/model/600129-lattice-vase

The printed lampshades just clip on the same way the orginal glass lampshade did - just remove the bottom layer and brim and your good to go.

PRINT INSTRUCTIONS //

• Both styles must be printed in Vase Mode
• 0.2mm Layer Height - the lattice is designed to print at 0.2mm, the regular can be any height
• 1 Bottom Layer - Purely for bed adhesion, I also added a brim, both removed after printing
• 0.6 to 1.0 mm Line Widths -  To strengthen the vase and allow for faster printing

I printed the lattice and regular versions using the alpha input shaper 5.1.0 for the Prusa Mini (I can't upload these gcode files here for some reason?) and in PolyTerra PLA - Cotton White.

UPDATE //

I printed the clear wavy version using the Bambulabs P1S in Bambu's PETG Clear

• I've included my .3mf file to include my PETG Clear profile and the print settings that worked the best for me.

I hope Prusa Slicer adds the option to generate perimeters like this in the future.
