This is a set of two pencils holders themed, based on the logos of Meltdown and Spectre vulnerabilities.
I have printed all the two pencils holders scaled at 50%, some differences for infilling and perimeters:
Meltdown: 10% infill 2 perimeters
Spectre: 25% infill, 4 perimeters or above, depending on nozzle diameter. It is not necessary increase the number of perimeters for strengthen the structure but to prevent the print head from being made to bounce too much during printing, increase it up to until the infill disappear from the outer walls of the ghost, the external walls must become made only of perimeters.
I designed the two pencils holders with FreeCAD, extruding the 2D SVG files from the logos into mesh objects, and subsequently cutted with a 20 degree angle on the top.
My work has made possible thanks to the availability of the 2D logos. The author of the logos Natascha Eibl has published her work on the website https://meltdownattack.com/ and released it under CC0 license, thanks very much for this!!!
FreeCAD source is available for edit / remix.
The battery cover is designed for work as replacement for remote controller transmitter that work with Jeep Wrangler Rubicon toy.
My son has lost it, i have designed and printed this thing for replace the orignal one.
It's simple to print, no special recommendations.

Bulldog Lite feeder on the FABtotum personal fabricator
The test is based on this setup:
FABtotum personal fabricator 1.0 FABui v0.93 FABlin 1.0.0091 Hybrid head 1.0 (j-head with 0.35 mm nozzle)
A new bowden tube is attached to the head and original bowden is still attached on original feeder.
I have made this simple adapter in order to use the Bulldog lite with the original cabling without make any modification and restore easily the original feeder.
Before start to print is necessary set the steps per unit for E axis with
command and store it into the EPROM with the
command (this operation is valid for FABlin firmware in the FABtotum but also for Marlin firmware on a generic RepRap printer).
The sample print is sliced with Slic3r, without using retraction.
The connector used in adapter was recovered from a broken CD-ROM drive board.
Special thanks to Gianluca Faletti (aka Kino), for hints on steps per unit calculation.
