Modified a design by Qwervy https://www.thingiverse.com/thing:2063412 to mount to the v slot on the ender 3 and ender 3 pro.

The printer will only go to 235 height without touching cutters in the holder. If you don't do tall prints it shouldn't be a problem.

I printed with the top facing down on the print bed with a raft for better adhesion because of the small surface area especially with rounded edges(Optional).

All my models are free, however, my Paypal is http://paypal.me/Stu142 if you wish to by me a coffee or help fund the failed prototypes of this model. Thanks!
