After completing my assembly guide on instructables.com, I wasn't expecting to be featured at all and it garnered a lot of attention around the world. Thank you so much instructables for doing that! I've been responding to a lot of emails during my week long vacation and had a few request to print a set for them. I figured I should sell some printed parts due to such high demand for them. I really hoped other reprappers would catch on and print a few sets too. If you're still having trouble finding someone to print a set, contact me and I can give you a quote!

| Glass switching |
I spent some time figuring out how I was going to print a few sets quickly and efficiently with only one printer. My Printrbot+ only uses 3mm and it's natural color so I didn't want to mix the colors up. One thing I thought about was figuring out how to streamline the print process. A print session usually requires me coating the print area with hairspray/elmers glue, printing, wait for print to cool, clean coating off and reapply. To counter this, I decided to purchase another boriscillate glass so that the moment a print is done, I can swap in a new one and start a new print while I wait for the prints to cool, clean the bed again and setup for the next print session.

| Print cooling off with Hairspray and Elmers glue stick combo |
The hairspray + elmers glue stick combo I've been using. I haven't had any of my prints curl for the past 3 months and it's been working great. I never got to see the parts from the bottom and was fun watching it shrink and pop off the glass bed.

| Print popped off without scraping |
Popped off right when it cools down. No more knifing that stuff out.

| 3DPrintMi's printed set |
11 print sessions in 2.5 days for a full set. Not bad, especially on a 152mm x 152mm print bed.

| SainSmart 1.75mm spool |
I took a gamble and purchased this 1.75mm filament off amazon for $31. It came in a cardboard spool which didn't really bother me, as long as the filament doesn't unravel during a print then it's all gravy. Not sure who sainsmart is but it's time to put you to the test!

| Printrbot Jr/Bukito frame experimentation |
Did some experimenting with my first prototype by messing around with the parts to resemble a Printrbot Jr/Bukito. After playing around with it, I don't think this will work. The linear bearings tends to flex whenever I press down on the X gantry so they are not the best application for this setup. The Z linear bearings would need to be stiff, maybe something like a polymer bearing or maybe bushings.
The next thing I'm going to try is to expand the frame to accommodate a 200mm x 200mm hot plate. This would definitely speed things up in printing out sets and I hope it will work. I think I have a few ideas how to make that happen.....stay tuned!
