Tower Simple XL Metric Miscellany
Collection of stand-offs and misc metric sized parts that were difficult for me to source in North America. If you have access to a 3D printer (I printed these at my local library!) these are quick to print and fit well.
Z-Axis 60mm End-stop Post: Fits to the YZ axis arm at the back. Don't forget an M3 8mm spring for fine adjustments
M3 6mm Nylon Standoff: Not in this collection (was able to source locally) isn't mentioned in the Instructable but in order to fit the LCD panel to the control box you'll need some 6mm stand-offs. Very tight clearance in this entire printer design (notice the LCD connectors bumping right up to the DRV88 boards)
Arduino stand-offs: Might not be necessary if you can find 4-40 8mm stand-offs (I couldn't) M2.5 6mm screws on the top secure to the Arduino Mega, M3 10mm pan-head screws attach the stand-offs to the bottom of the box
X-Axis Bed Stand-offs: For the bed-leveling springs. Uses 4 M3 10mm screws.
Filament Roll Holders: Couldn't find the exact metric sized PVC tube needed to fit the bearings in Canada, so I just 3D printed it!
