Corner Bracket for a Glass Bed on a Makerbot Replicator 2 and Its Clones This bracket is designed specifically for a 1/4" glass plate, but can be used with thinner glass as well. Any tips or tricks to use or improve the design are welcome in the comments section! Your feedback is greatly appreciated! Update: August 28, 2016 - I have added a version without the adjustment slot. Print Settings: Printer: Qidi Tech Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 50% Notes: Due to temperatures, this really should be printed with ABS and not PLA. Post-Printing: Additional Non-Printed Hardware: You will need the following in addition to at least two of the printed corner clips: 4x M3 x 20mm screws (2 per corner) I used socket head screws because I couldn't find any thumb screws. 4x M3 nuts (2 per corner) 2x M3 x 15mm screws to replace the ones protruding underneath the heated bed. My bed used flat head screws. 2x M3 wingnuts (1 per corner) Installation Instructions: Print two of the new corner brackets. Slide M3 nuts into the two slots on the top. Screw in the M3 x 20mm screws from the side. Remove your heated bed assembly after it has cooled. It's easier to work with if you don't have to reach into your printer. Remove your PCB heating element from the aluminum build plate. Remove anything that is on top of your aluminum build plate and clean it. Mine had a large plastic sheet on it, which I removed using Goo Gone in a cookie sheet to remove the glue. Reassemble the heated bed assembly, making sure to replace 2 of the corner screws with the longer, 15mm flat head screws using the same nuts. It doesn't matter which two corners you choose, but they need to be on opposite sides. Slide the newly printed corner brackets over the longer screws and use wingnuts to secure them. Put the heated bed assembly back into the printer. Place the glass bed on top and tighten it down with the screws on the corner brackets. Take a picture and post it on Thingiverse. Level your bed. Print some awesome stuff! How I Designed This: I bought a glass bed for my Qidi Tech, assuming that the bed was the same size as on the Flash Forge Creative Pro. It's not, though - the Y-axis is about 1/16th of an inch shorter. Determined to use my piece of glass and unable to find corner clips that would work for my situation on this printer, I found some designs that might work if they were bigger (by austingeorge and albertkoey). I designed this version for the Qidi Tech, but it should be compatible with any of the Makerbot Replicator 2 clones like the Flash Forge Creative Pro. Tips and Tricks: Loctite: I put a drop or two of blue Loctite on each screw before threading them back in and securing the bed. This came after a few prints came out ruined because the build plate started moving due to the screws loosening. Just make sure that the Loctite you buy can handle the temperature - some might melt ABS and weaken the part. All Four Corners Instead of Just Two: After installing the glass on mine, I noticed that the glass was secure and wouldn't move, even after running a print. However, it was not square with the bed. I decided to not put brackets on all four corners, but it could easily be done while the heated bed assembly is apart. If you choose to take this route, you will need to double the quantities of all the parts above and complete step 7 of the installation instructions twice on all four corners.
