This is a generic Widgit Banger! I (Mr. Bunny) made it because it's cool but I use it to make Widgits. Share and Enjoy! (This page was made using the wiki page Development:Example as a model.)


I have finally built my second repstrap. It’s features are

1) Low cost. Uses screws instead of nuts and bolts and MDF not plastic and steel. 2) Bearing count 23. But I recon I can get it down to 12. 3) 8 threaded rods+2 unthreaded rods but it can be reduced to 5 + 2 unthreaded

4) 300 x 400 Z axis build area. With a Z axis of 250mm 5) Prints well at 25m/s with a Makerbot MK4 extruder. 6) Happily go to 50m/s but the extruder can't keep up

7) Darwin design but uses only three threaded rods on Z axis. 8) Z axis is rock solid.

9) Big red emergency stop button to be wired into Reset pin of Arduino 10) Nice area in the Z axis to dump spanners and often used tools. 11) It is so robust I can sit on it. (I am about 95kg)

Just thought I would share.


P.s. I have attached pictures.

Entrepreneurship (Kits)

There is no kit. This machine was built using two Saws, Pillar drill, a Screw driver, two 13mm spanners, a big metal ruler, glue and lots of G clamps.

Where accuracy is required I cheated by using pre cut MDF. For example the two uprights bits of MDF needed to suppot the x-y printing bed obviously need to be exactly the same size. (otherwise it would lean) I bought a 900mm x 450mm bit of 16mm thick MDF and cut it in two. This gave me two bits of MDF with a perfect 450 side and a rough 450 side. The perfect 450 was used to hold up the X-y printing bed with the roughly cut 450 points outwards to the back of the system. As a result I did not choose the size of the machine my MDF supplier did. My MDF was supplied in 900x450x16 and 800x600x16.

The machine has a base of 800x600 with a x-y printing bed of 800x600 which sits exactly 450mm high. If your MDF supplier has different sized MDF this should not be a problem. Just go with the flow.

Files and Parts

Generic/Daughter_part and CarrotStraightener. (As a gentle style recommendation, it's good to try to keep all your parts and files on the RepRap wiki rather than scattered around so that Mr. Bunny doesn't have to use a scripts and so on to get stuff back onto the wiki.) File:Uploaded files
