Proxxon 28606 (MB 140) Backpack and Springtensioners

thingiverse

So we have this old Proxxon MB 140 Stationary drill at work and it needed some help at its work. The spring did not have enough power to push the drill back up and the drill heads were laying all around the place. Long Story short: I designed a little backpack for drillheads and other tiny tools you might need close to the MB 140. You can easily slide the backpack onto the main pole. The rings are meant to be placed underneath the spring (on top might also work). Just slide the whole mechanism up and off of the main pole, place a ring in between the parts and slide it all together back on. Done. The 5 mm ring was enough for our tool but in case your spings are even worse, i also added a 10 and 15 mm version.
