Test Tube Holder (for Prusa i3)

This is a variation of my Test Tube Holder (for Prusa Mendel) thing, which allows you to securely and conveniently mount a test tube to your printer. (I use test tubes to hold ABS juice, which I use to prepare the print bed for prints.)

This version is modified to fit the Prusa i3 cut from 6.5mm MDF, and it incorporates nut traps so you can use M3 screws to hold the pieces securely in place. Let me know if you need other thicknesses, and I can either change it or get the OpenSCAD file ready
