MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I did have to recreate the parts to solve for some discrepancies from U.S. (Amazon) supplied parts. Here are the parts used to build my version of this tool.
12.7 mm digital micrometer (https://smile.amazon.com/gp/product/B01LC821H8/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1)
624 ZZ ball bearings (https://smile.amazon.com/gp/product/B00AUB7M3C/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1)
0.062" x 0.5" x 1.75" compression spring from this kit (https://smile.amazon.com/gp/product/B00VDRF25C/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1)
MGN9 100 mm rail w/ MGN9c block (https://smile.amazon.com/Linear-Guide-Length-100mm-Motion/dp/B01IOS2MD2/ref=sr_1_14?ie=UTF8&qid=1523374444&sr=8-14&keywords=mgn9c+rail)
Miscellaneous metric screws and bolts
0.20 or smaller
30% or more
Printed mine in PETG with 0.14 mm layers, but bigger would have worked also. Three perimeters and 30% infill, the only part I used supports on was the channel for the linear rail.
I actually made two of them identically after printing the first one 'as is.' That print job was put in the recycle bin after ordering the parts to finish it. When I sourced the parts I needed that was when I started to fiddle with the design to make the parts I had fit.
Nice one! Thanks for making! What exactly did you change?
I used a different dial indicator that required a larger recess, and I had to lengthen the slot for the linear rail since the length you specified could not be found easily in the US at resonable costs and was lengthened to 100 mm. That is why it is longer than your version. I may rebuild it with a much shorter rail if I can find one cheap enough.
Thanks for information! I will keep it in mind for improvement. Is there a reason why can't you cut of the rail to the needed lenght?
Gotta love honesty!
When I sourced rails under 100 mm the costs climb astronomically, don't know why. That is why I chose a 100 mm rail but the reality is even the 70 mm rail that the original poster used is too long, the amount of travel is probably less than 30 mm total. If I redo this I will cut the rail in half and only use 50 mm just to make sure.
But I just didn't want to go though the trouble of cutting any of the pieces.
I also remodeled the whole thing, since only STL files were provided and I hate working on meshes. So if anyone wants the 3D source files I will post them.
I remodeled all the parts in Fusion360.
Ah okay :D
