Modified and split Z-stage for Ultimaker 2 Aluminum Extrusion 3D printer

thingiverse

I've been working on the Ultimaker 2 Aluminum Extrusion 3D printer on a small printer, so I had to split up the parts to be able to print them. There are two different top and two different bottom pieces. The names should clearly indicate what they are. There are two different bottom middle pieces (motor-mount) where one is shortened a bit in case the three pieces making up the bottom get a bit wide. Changes: Top 1.1) Top of Z-stage has been split into two. 1.2) A hole for an M3 screw was added to each top part. You need to add two extra T-nuts. 1.3) The 12mm rod holes were enlarged to 12.4mm to make them fit after 100% infill, which I strongly recommend. 1.4) Some built-in support was made in the 12.4mm hole to make it cleaner. It's easy to remove afterwards - you can use support in addition if you need it for the longish hole in the parts. 1.5) One version of the top pieces has a 2mm deeper hole for the 12mm rod (hole is still 12.4mm) and I lengthened the piece to move the location of the nut. 1.6) I accidentally uploaded a version of the top.right side with built-in support. Use it if you like, same as the other extended model otherwise. Bottom: 1.1) The bottom Z-stage was split into three parts. 1.2) The 12mm rod holes were enlarged to 12.4mm to make them fit after 100% infill, which I strongly recommend. 1.3) The hole for the motor in the bottom of the middle section was filled up as it made for manual cleaning and enlarging. The motor fits just fine underneath it still. (I use a 40mm motor, but larger motors should be fine when you use feet on your case.) 1.4) One version of the left and right pieces has 7mm deeper holes for the 12mm rods - holes are still 12.4mm in diameter.
