Monoprice Select Mini V2 Fusion 360 CAD Model by Kadah

Last crawled date: 3 years ago

Do you make mods for the MPSM and find it pain having to constantly reference your printer to dimensions, or worse, have to keep taking it apart to recheck some internal dimensions? Well I took apart mine to nothing and sketched everything so you don't have to.
This is a (hopefully) accurate Fusion 360 model of a MPSM v2 that seems to reperenst most reversions sold around the mid 2017 and later. Early v2's had a few minor differences. This may also mostly apply for v1 as well, but I never had a v1, so YMMV.
For shits and giggles there is an STL version on this thing, and the f3z export of rev11, but the actual current model can always be access via this link: http://a360.co/2A7naPE
Most things should be within +/- 0.1mm, which is less than what I can say about my Mini's construction. If you find an error, please leave a comment so I can fix it. I've been correcting the model as I work on some mods. I think I have it nearly complete now.
Things not modeled currently / Todo:
Extruder and extruder stepper
Hotend, but printhead is otherwise complete
Y idlers, stepper, or belt (unlikely to do belt, but might added a mockup stand-in later)
X stepper or belt
X idler (need to measure next time I have it off)
Spool holder (haven't seen a reason so yet)
Control board mockup
Cabling (yeah, no, lol)
Unicorns
Update 2017-12-08:
Added a stand in stl model for use with slicers that have the functionality to show a model of your printer. Origin should be set to 0,0,0. Untested, I don't use such a slicer myself.
Update 2019-07-13:
Fusion 360 finally supports exporting linked designs. I have exported the latest version of the main assembly, as well as each of the major sub assemblies, to the following formats: f3z, iges, step, and skp.
I have tested the skp files in the SketchUp Viewer and they appeared to work. Similarly, I imported the iges and step back in to Fusion 360 and those worked as expected.
The f3z files for Fusion 360, upload it in to a new folder, or new project, as each f3z file contains all the sub-designs in it. It is only necessary to import the "MPSM v2 v11.f3z" if you need the entire model, and it contains the major sub-assemblies as well which are easier to work with. There are 40 separate designs/assemblies in this file, it will take a while to import.
Note on x-axis rod spacing:
I believe 30mm is the ideal intended distance, however on mine the center-to-center distanced is 29.91mm +/-0.01mm on each end. This causes print heads using a spacing of 30mm to be too tight at end of travel.
If you are going to design a print head, for best results, either: measure the rod spacing (from outside-to-outside and subtract 6mm) on your actual printer and use that, or design your lower bearing holder to have slight vertical adjustment (something similar to an i3 style may work).
Tips for working with the model
With Fusion 360, it's a better idea to start a new design and drop in links to the sub-assemblies you require. This will keep the design much clearing (especially the timeline). Just set the top level component as active and drag needed sub-assemblies to the component tree. Hide unneeded components.
