I'm pretty new to 3D printing, and when I first printed the one yours is based upon, it failed due to the model curling as it started to print the rounded top.

What problem(s) does your horizontal rods fix?

On an FDM (filament) printer, horizontal things such as you show, are very hard to print, as when you start you are "printing on air". Only a VERY careful set of adjustments possibly with modified cooling fans, nozzle temperature, speed of extrusion, might that work.


hi, i made this remix because I only needed that element without the other complemetary pieces, the rods are only supports that are discarded later. You are right, the rods are difficult to print, they only serve so that the piece does not break before finishing, i added because i didn´t want to print with program supports, it would take more time.

I hope I've helped.

Oh! Prevent breakage - thanks!

Apparently you ran into what I ran into when printing with inexpensive ($12/KG) filament: It would curl so much that the nozzle would hit the curled up end of the start of the top, that it would knock that leg loose from the build plate!!!

An alternate solution seems to be to use a better brand of filament. I used Hatchbox with the original model, and it printed perfectly -- enough less curling that there was no problem that way.

See picture of mine breaking.
