Adesina - A Wooden Mendel RepStrap
Note: Mendel is optimized to be printed. WolfStrap is optimized to be made from wood. If you're making a machine from wood, consider WolfStrap. And then make a Mendel from wood anyway, for aesthetics and love of the art. --Sebastien Bailard 03:27, 22 July 2010 (UTC)
Say hello to Adesina
Adesina is a Nigerian name which means "first of many children" or "she opens the way". She is a Wooden Mendel RepStrap, built close to the likeness of the official Mendel. Although some parts have been modified to better suit a wooden construction, the idea is to be able to print Mendel prostheses for Adesina, if needed. The original worklog is posted at this Norwegian forum. Pictures are in spoiler tags throughout that thread.
Ideas and feedback in the reprap.org forum thread is very much appreciated!
Update 2012.07.21 - Adesina is getting rebuilt with proper printed parts.
A more thorough build log with notes will be made here when Adesina can print. For now, please refer to the pictures in the running worklog.
The heater barrel, nozzle and PTFE barrier was bought from reifsnyderb.
Inspired by  here are the first test with molding gears with polymorph thermoplastic suitable for a T1.5 belt from an old AGFA snapscan. The initial results was really great, very simple to make and fully mechanically functional. A modified mold design is tested, which produces gears a bit simpler and faster.
The bed and x-axis have been simplified. The rest is as close as possible to the original Mendel parts.
Version 4 seems to be working. Not tested with proper belts, gears or motor though. This versions have more measurements, and some commentaries. Please look at the photos to understand where the different parts go.
No frogs have been squashed in the process of making this bed.
There are some tools which felt invaluable to build Adesina.
- Drill press
- You need to be able to make straight holes. A cheap ~70$ was used here, which works just fine.
- High quality drill bits
- Cash out for a good set, you will not regret it. A ~100$ set on sale is worth it. (150$ retail, Norwegian prices).
- Band saw
- A friend used his band saw on some of the more difficult, precise cuts. Thanks!
- Useful with many cuts when you don't have a band saw available.
- Put on a new blade, and it's a breeze to use. Good for thick sheet.
- Mitre saw
- Good for the more heavy, precise cuts from your stock wood.
Approximately 1000$ (~$180 USD). (Not including tools already in the workshop).
Here is a Google spreadsheet with all expenses. The currency is NKR (Norwegian kroner). Norwegian language only, "delenummer" means part number.
When possible, local suppliers was used.
Plastkompaniet AS was not able to supply PLA.
