I have just broke my second acrylic piece, and am currently unable to print. would someone be willing to print this for me. I have a paypal account, just let me know the cost and shipping. Any help would be greatly appreciated.
I printed and installed this...
The top of the hot-end was tweaking the alignment of the lower piece, so I had to do some precision sanding to get it to fit nicely.
Using the acrylic tensioner arm, I was repeatedly getting filament bending out forward of the pinch-roller section, and thus losing 100% traction and killing my prints. The filament feed path just didn't line up properly...
the following adjustments got it working 100%:
1) I had to shift the hobbed pulley forward about half a millimeter.
2) I had to file the back end of the mount point @ the tensioner arm pivot point, and shim up the front with a tine washer, thus shifting the whole tensioner arm forward.
3) took apart the tensioner bearing, and moved one washer from the front to the back of the bearing - shimming the tensioner bearing forward.
With just a few tweaks, Lawsy's masterworks have made my SoliDoodle 1 step closer to being a nice manufacturing-grade machine. You rule!

Lawsy, I noticed in the SKP there is an extruder fan shroud with PEEK cooling as well as material cooling. Why was it never posted on its own?
Thanks for pointing this out, I modified it for a 40mm fan and posted it. Hoping it works well, printing now.
