P3steel 2.5 - RAMPS Offset Mount

thingiverse

This is a remix of the P3steel 2.x - RAMPS offset mount by Toolson for a RAMPS/MEGA board, but specifically designed for a 2.5 DXL laser cut frame with its electronics mounting holes configured slightly differently than the 2.0 and 2.01 frames. Similar to Toolson's version, this allows some offset to add in an LCD/SD adapter into the RAMPS board and gives you better access to the electronics. If you use a P3Steel with a 2.5 DXL frame, you may not notice that both frame uprights have different hole configurations, and these configurations also appear to be different from those of the 2.0/2.01 frames. If you follow the traditional layout, the RAMPS is mounted on the left as you look at the front of the printer, on the outside. You need to find the upright frame panel with matching holes to your Arduino Mega 2560 board - that's your left upright. If you use the other upright frame panel as the left and try to match up the Arduino to the mounting holes, it won't line up. So assuming you have this configuration, if you use Toolson's mount, you may find that the frame mounting holes just won't align. Toolson's "Toolson Edition" Prusa uses a 2.01 frame. Use these files to create the correct mount. I've included both a full-size version and also (just like Toolson!) a diet version which saves on filament and print time. The diet version may also help with corner curling issues too, as they are two smaller pieces rather than one large piece. Please share your makes if you make one! UPDATE: 16th June 2016 Time lapse of both prints: https://youtu.be/99uBQ1ShJvY UPDATE: 16th June 2016 New STL uploaded p3steel2.5-_ramps_10mm_offset_mount_super_diet, which is now only a 10mm instead of 15mm offset as I think the 2.5 DXL frame has more room towards the frame. This file also has even more trimmed off it to the bare minimum needed to mount the Arduino to the frame. UPDATE: 20th June 2016 p3steel2.5-_ramps_10mm_offset_mount_super_diet printed and installed now, see the last few pictures in the gallery. This part is a filament reduction but also moved the mount in 5mm so there's only a 10mm offset - and this brings the mount in to not stick out the side anymore. The LCD adapter is still accessible and works fine.

If you're using the 2.5 DXL frame, the Arduino is mounted to the frame with M3 bolts and a hex nut. I used a nyloc nut to secure it in place and also an M3 washer to help not nip the frame. How I Designed This This is a remix of Toolson's part, but it was more of an exercise in learning Tinkercad. Using the original part measurements, specification of the frame, M3 bolts/nuts, and the Arduino mounts, I fully replicated the part within Tinkercad. After a couple of designs and prints, I finalized it to what it is now. It's surprising how simple yet comprehensive Tinkercad is, and it's ideal if you just need to "knock up a bracket" in a matter of minutes!
