Typhon's Airtripper BSP for MakerFarm i3v / M3 Mount by typhon3d

Last crawled date: 3 years ago

This is a modified version of Airtripper's great Bowden Extruder featuring the BSP fitting. I modified the design to work better with the MakerFarm i3v and it's existing hardware included with the Wade's geared extruder kit. I also made the mounting holes for M3 screws as they are usually more abundantly available to those using the Prusa i3 and i3v models.
The main mods made here are as follows:
1: The mounting legs were extended so the screws can easily be accessed from the top of the unit. This is especially important when mounting them directly into a tapped hole instead of a nut and bolt system the original Airtripper design used.
2: the mounting holes were shrunk to use M3 screws as most users of the Prusa model printers would have extra M3 screws available.
3: the 25mm screw mount was extended to 30mm to make it more uniform and to allow the use of 3 M3x30mm screws instead of 2 30mm and 1 25mm (easier to source parts of the same size than multiple different sizes)
4: I created a custom mounting plate to mount the unit above the left z axis rod on the MakerFarm i3v (This part is optional and only designed to work with the i3v 8" by reusing parts from the wooden spool mount)
5: I tried to reuse some parts from the Wade's extruder like the springs and 50mm screw to tension the idler, the 20mm M8 rod for the bearing and the 3 10mm screws used to mount the motor to the Wade's by using them with the mounting plate and the BSP connector.
Hardware needed:
3 - M3x30mm socket cap screws -- 1 included with the i3v
1 - M3x6mm button cap screw
3 - M3x10mm socket cap screws (5 if using the included X Plate to mount to MakerFarm i3v) -- 3 included with the i3v, the other 2 can be a bit longer if 10mm not available
2 - M3x45-50mm screws -- M3x50mm included with the i3v
3 - M3 washers
3 - M3 nuts -- included with the i3v
2 - high pressure compression springs -- included with the i3v
2 - M3 lock nuts -- Only if using the M3x50mm screws from the i3v

I hope this helps anyone who wants to use the airtripper design with their MakerFarm i3v
More pictures will be added soon of it mounted
Let me know what you think and any improvements I could make!
Thanks
