Release status: Experimental
This page is the home page for this project, you should be able to find links to all files, instructions and videos needed to create a LaserCut Mendel of your own.
If you are cutting your own, you need to know that there is some ADVANCED post-processing of parts with a router table and drill press. You will also need to build some jigs to perform the post-processing accurately.
The creation of the files represents over a hundred hours of work, so if you are not purchasing any items from TechZone, please consider making a donation to them so that they can continue developing and providing technical support for the RepRap community.
Description of Differences
Although the frame is essentially identical to the standard Mendel, there are some notable differences.
1. Hardware differences: The LaserCut Mendel uses far fewer m4X40 bolts (and less bolts in general), but it uses more of the m4X16 bolts. There are also 2 fewer bearings on the Y axis - technically you should be able to also leave these same bearings out of the original Mendel without impacting performance. We also use far fewer m3 bolts. We also need 8 pieces of 40mm X m4 studding
2. X Axis We have reduced the number of parts, and merged pieces, in order to simplify the assembly out of sheet goods. We also changed the way the bearings mount up, they now rely on the "spring" capabilities of the plywood to apply pressure to the smooth rods (we have done this on all the axis).
3. Y Axis The bearing mounts have been changed here (similar to the other axis). The "Frog" plate has been altered significantly to accommodate the new bearing mounts; if you intend to convert this machine to a true Mendel, you will need a "stock" frog plate.
4. Z Axis The Z Axis is probably the least changed, but requires the most post-processing of cut pieces.
5. Frame I mention the frame here so that no one thinks I forgot to mention it... It is relatively unchanged, and the pieces should be a near identical 1:1 replacement
Depending upon how you create/acquire your Pieces, there are several major steps to build your RepRap.
1. Acquisition of parts. Information on all the parts needed to build a LaserCut Mendel Repstrap, what to get, where to get them, or how to make them.
2. Raw LaserCut parts need a fair bit of post processing, with clamps, glue, a drill press and a router table to get to an assemble-able point.
3. Ready To assemble parts need assembly into the device shown at the beginning of this wiki article. Refer to the LaserCut Mendel Assembly page (which is currently a work in progress) and the LaserCut Mendel Assembly Blog.
5. Print something!

The following files are the original design files, in CorelDRAW format.
This is all three of the CorelDRAW files in one zip.
Here are the three files in SVG, a more widely used and portable format.
Z Axis Motor Bracket
- Version: as of 23rd September 2010
- the shape of the motor bracket plate is not correct
- two small pieces are missing (respectively they don't have the right shape)
