So we hit a snag with the Bowden extruder design on the DIY 3D QU-BD Twoup, the back and forth action has worn out the pressure fitting on top of the hot end leading to premature failure (half a spool of plastic). So watch as we try to figure what to do!
As in this episode we will be cover the many modifications made to the QU-BD TwoUp DIY 3D printer. As we have re done the The Y, X and Z Axis as well as have added bed leveling too Whew!
Here are some of the Thingiverse Links:

This is a remix of a design on Thingiverse for the QU-BD OneUp and TwoUp DIY 3D printer to hold the Y Axis belt from slipping. In this design we have added recessed openings to receive #6 nuts and we highly recommend adding this build to your QU-BD OneUp or TwoUp printer to prevent the belt from slipping during fast rapid infills of the Y Axis.
In this episode we start the build of the self-leveling servo & switch combo for the QU-BD TwoUp DIY 3D printer we built a while back. Our hope is this will improve the quality of the prints our prints by adjusting for the level of the QU-BD TwoUp bed. We also have listed the parts below we got from Amazon.

M2 Screws: amzn.to/1LMTpBI
In this episode short we build spring caps for the leveler springs of the QU-BD TwoUp DIY 3D Printer to prevent the bed from slipping during rapid moves typically found when doing in fills when 3D printing objects. You can also find this on Thingiverse at (www.thingiverse.com/thing:1079696)!
So we have been working on the QU-BD TwoUP 3D DIY printer again and one of the thing which we made where retaining cups for the bed springs. We where having issues with the prints shifting as there was play in the (few thousands of an inch) and when the printer did infills the alignment would jump as the bed shift (assume it slid on the springs). With any luck this will reduce the issue. Also keep eye out for a video on this too.
In this project we design four 1 inch diameter feet for use with common 1/4 Inch bolts to make adjustable feet for any DIY project you might have. As we searched Thingiverse and really could not find anything like this. Worth note, is the adjustable outside is 9/16th of inch while the inside is slightly over sized of 1/4 inch to allow for epoxy (we recommend JB Weld). As epoxying the bolt head (on all sides lightly) before insertion will make the metal bolt part of the over all structure add greatly to the strength foot and while on the topic would print with at least a 50% in-fill. Also notice we add support around the bolt head base for extra endurance.
In this episode we are going to watch as a hex bit holder is 3-D printed on the QU-BD Twoup printer. This is a handy shop project and something that was easy to print which provided a lot of value around the shop and you can check out the STL file here on Thingiverse (www.thingiverse.com/thing:1018141/#files)
In this episode we will install the glass bed hold clamps from the last post on our QU-BD TwoUp DIY 3D Printer… TwoUp 3D Printer Kit 7″ x 7″ x 5″ Build Dimensions 50 Micron 1.75mm PLA Filament by Q3D…

In this episode we will look at building a set of hold down clamps for the QU-BD TwoUp 3D DIY Printer kit. As you might recall we where having issues with the melamine bed so we switch to glass however the shaking of the when doing in-fills was ruining the prints so we designed a set of clamps to hold the glass in place firmly. The glass bed is 11.5 inches long and 7 inches wide. We left a little room length wise as we want to add thumb screws to the bed for leveling in the future. In addition, the glass is +/- 0.16 inches in thickness and the clamps are 4 inches wide.
