Print Rite DIY 3D Printer - Adapter MK2 MK3 Heat Bed

thingiverse

It's an adapter for the MK serie Heatbeds and the Print Rite 3D Printer. Original bed is 21 x 21 cm MK3 bed is 21.4 x 21.4 cm It involve cutting 1cm from the corners of the original Acryl-bed (pictures will follow). 27/11/2015 I already printer the part, M3 screws comes nicely threw. I'll prepare the orginal bed and set the screws and make some pictures later on to confirm the design. Ok! everything is in place. The part is validated ! Tomorrow I'll get the new PSU 12V - 15A, we'll see how it goes ;) 28/11/2015 Z axis stopper screw is to small, you'll have to use a M5 x 80mm. I designed a part to get a better stability for the screw. Work nice. I also added two nuts to secure the screw. See pictures ;) 01/12/2015 New PSU connected (12V-15A). I reach 100°C after 18min. Ill try to get 13V out of it to reach 110V. I didn't manage to print onthe bare luminium surface, I had to spray som hairspray on it to get a grip. Still got some very light warping with ABS at 100°C Heatbed. The PLA corners are holding the 100°C fine, the heat is not propaging downwards, so worries there. The heat bed spent at least 3 hours at 100°C, and there was no problem with the corner parts. 03/12/2015 So, there is an pot on my the PSU (It's a PSU designed for LED stripes 12V15A) and I set it so that I got 13V on the Hetbed connectors. It means the the PSU delivers 13.4V to the Printer. But it manage everything very well. With this setting I can now reach 110°c easily. It still needs 12 to15 minutes, but the curve look nice, not as it were struggeling at all to come there. ABS is not warping anymore at 110°C, I'm printing diretly on the aluminium with Hairspary and a 5mm brimm. 14/01/2016 I made a new version so we can add a part like this one:http://www.thingiverse.com/thing:874155 for bed levelling. My problem is the head of the inside screw. I put some more height. See the picture ;) 14/01/2017 I found this part on the printer group:http://www.thingiverse.com/thing:1659738 Seems to be a better option :) I'm still using my old one, but if I had to do everything again, I would give it a try. Print Settings Printer: Print Rite 3D Printer Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2 Infill: 50 Notes: At the moment the parts are PLA. How I Designed This I get the part inspiration from this Blog: http://lbsfilm.at/print-rite-diy-a-3d-printer-from-hobbyking/ Thanks for the idea ! I just rebuild the part, adding 3.5mm holes at the right place.
